[SOLVED] How to flush DNS cache on a Mac
Flushing your DNS cache is an efficient way to troubleshoot DNS and connectivity issues, as well as keeping the local record of domain name server information more secure. In this blog, you’ll learn what DNS cache is, how DNS cache works, why you should flush DNS, and most importantly, how to flush DNS on your Mac.
How to flush DNS on your Mac
To flush DNS on your Mac, you’ll need to enter a Terminal command on your Mac. Here’s how to do it:
- On your keyboard, press Command and Space to invoke Spotlight.
- Type terminal and press Enter to launch the Terminal app.
- Copy and paste the following command into the Terminal window, then press Enter.
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
Note: this command only works on macOS EI Capitan and newer. If you’re using an older versions of macOS, check the next section for the correct command.
- You’ll be asked to enter your Mac’s login password to run the command. Just enter the password and press enter again. Please note that due to security reasons, the password will not be displayed when you’re typing. There’s no notification when the process completes.
Note: if you’d like to hear an audio notification after the NDS flush process completed, run the following command instead:
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder; say dns cleared successfully
Flush DNS commands on older macOS versions
The table below lists the correct commands for resetting DNS cache on older macOS versions:
|macOS version||Terminal command|
|macOS EI Capitan and newer||sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder|
|Yosemite||sudo killall -HUP mDNSResponder|
|Lion, Mountain Lion, and Mavericks||sudo dscacheutil –flushcache|
|Snow Leopard||sudo lookupd –flushcache|
What is DNS cache and how it works
DNS, or the domain name system, is the phonebook of the Internet. It translates human readable domain names (e.g. techzoneonline.com) to machine readable IP addresses (e.g. 123.456.789.1), connecting web browsers with websites and allowing browsers to get to websites and other Internet resources. Without the DNS, we’ll not be able to visit a website by its domain name. We have to manually enter the IP address of its web hosting.
The DNS cache on your Mac is a temporary database that stores information about previous DNS lookups. It’s like a phonebook at your hand.
Anytime you enter a URL into your web browser, or click the hyperlink on a webpage, a DNS lookup process is initiated. If it’s the first time you visit a website on your Mac, your Mac will connect to a DNS server that tells your web browser where to go (which IP address your browser should go) .
The DNS server maintains a directory of websites and their corresponding IP addresses. When your Mac connected to a DNS server to fetch the IP address of a website and provides it to the web browser, that information is stored on your Mac in the DNS cache.
In other words, every time you visit a website, your operating system and web browser keep a record of that domain and corresponding IP address. This eliminates the need for repeated queries to remote DNS servers and allows your OS or browser to quickly resolve a website’s URL.
Why you should flush DNS
There are several reasons to flush DNS. The most common one of which is to make sure the DNS records in your local cache is up-to-date, to resolve DNS errors when trying to visit specific sites, and to protect your Mac from NDS cache poisoning and spoofing.
Hopefully, after reading this guide, you’ve learned how to flush DNS on your Mac. Feel free to drop a line in the comment area below if you have any questions or suggestions on this topic. Thanks for reading!
It’s quite annoying to find your mouse is becoming laggy and jumpy when you want to get some serious work done. If you’d like to fix the slow mouse performance issue and get rid of a laggy, jumpy, choppy and even unresponsive mouse, you’ve come to the right place! This post is a comprehensive troubleshooting guide that works on any Bluetooth mouse like the Apple Magic Mouse, Logitech Bluetooth mouses, etc.
- Do some basic troubleshooting steps
- Make sure your mouse is charged
- Clean the bottom surface of your mouse
- Make sure you’re using the mouse on a flat surface
- Turn off your mouse and turn it back on
- Unpair and re-pair the mouse
- Restart your Mac
- Remove any USB device connected to your Mac
- Remove any new wireless electronic device nearby
- Disable and re-enable Bluetooth on your Mac
- Adjust the tracking speed & scrolling speed
- Disable Handoff Feature
- Reset your Mac’s Bluetooth module
- Delete Apple Magic Mouse related Bluetooth property list files
- Reset NVRAM
Do some basic troubleshooting steps
Before trying anything more complicated, let’s do some basic troubleshooting steps first.
Make sure your mouse is charged
Unlike the wired mouse, the performance of the Bluetooth mouse is affected by its battery status. If your mouse isn’t charged or has worn out batteries, the cursor will be laggy and jumpy.
Clean the bottom surface of your mouse
Make sure the bottom surface (especially the IR light sensor) is clean. A Magic Mouse 2 user reported in Apple Support Communities that if there were pieces of lint or hair in the cavity containing the IR light sensor, the mouse will become laggy.
You can use a soft, dry cloth to clean the railing and remove any debris from the laser opening of the mouse and see if it lags again.
Make sure you’re using the mouse on a flat surface
The mouse may not work properly if you use it on a bedsheet and such uneven surfaces. It’s suggested that you use your mouse on a flat and clean surface.
Turn off your mouse and turn it back on
Most mouses have a power button. You can turn it off, then turn it back on to see the mouse lag issue persists. You can also pull out its replaceable battery and reinsert it.
Unpair and re-pair the mouse
Sometimes the mouse lag issue would be fixed after you re-paired your Bluetooth mouse.
To re-pair the mouse, you need to unpair it first. Here’s how to do it:
- Go to System
Bluetoothand remove your mouse from the Bluetooth devices list.
- Re-pair your mouse according to the mouse pairing tutorial.
Restart your Mac
Restarting your Mac often can fix temporary glitches like laggy mouse input and irregular mouse cursor. By restarting your Mac, you’re performing an SMC reset, which may help fix the wireless keyboard / mouse lag issue.
Remove any USB device connected to your Mac
If you have any USB device connected to your Mac and your Bluetooth mouse happens to be laggy and jerky, try removing those USB devices.
According to the white paper “USB 3.0* Radio Frequency Interference Impact on 2.4 GHz Wireless Devices” released Intel in April 2012:
“There is degradation in the performance of the wireless mouse when a USB 3.0 device is connected to the notebook computer. At a distance of 3 feet and greater away from the notebook computer, a significant lag was experienced in the response of the mouse. The impact to mouse performance was found to be the same whether the USB 3.0 peripheral device had data being actively written to it or if it was merely connected to the notebook computer and the link to it established.”
“A similar impact to wireless mouse performance was noted if a USB 3.0 device, such as a flash drive, was used. Since the noise from the USB 3.0 is broadband, it could potentially impact any radio whose antenna is close by. Although the test results are not shown in this paper, similar impact was seen to Bluetooth radio performance.”
Remove any new wireless electronic device nearby
If there are any new wireless electronic device nearby, it may cause interference to your Bluetooth mouse. To rule that out, try keeping any new wireless electronics farther away from your mouse and Mac.
Disable and re-enable Bluetooth on your Mac
Sometimes the Bluetooth mouse lag issue would be resolved after you re-enabled Bluetooth on your Mac. To re-enabled the Bluetooth function on your Mac:
- Go to System Preferences > Bluetooth, click Turn Bluetooth Off to disable Bluetooth.
- Wait for 30s and click turn Bluetooth On to re-enable Bluetooth.
Adjust the tracking speed & scrolling speed
If the tracking speed of your mouse is set to a low volume, the cursor would be lagging or moving slowly. You can follow the steps below to adjust the tracking and scrolling speed of the mouse:
- Go to System Preferences > Mouse, under the Point & Click tab, move the slider under Tracking speed to the right to increase its tracking speed.
- Go back to System Preferences > Accessibility, on the left sidebar, scroll down to click Point Control, then click Mouse Options…
- Move the slider next Scrolling speed to the right to increase its scrolling speed. Click OK to save the changes.
Disable Handoff Feature
Some Mac users have reported that the Handoff feature would interfere with the wireless mouse, and they fixed the mouse lag issue by disabling the Handoff feature on Mac. If you don’t need the Handoff feature on your Mac, just follow the steps below to disable it and see if this fix the mouse lag issue:
- Go to System Preferences > General.
- Uncheck the box next to Allow Handoff feature between this Mac and your iCloud devices.
Reset your Mac’s Bluetooth module
You can try your luck to reset your Mac’s Bluetooth module if you’re still having the Bluetooth mouse lag issue.
Note: Your Mac’s Bluetooth module will be reset to its factory settings after you reset its Bluetooth module, which means that the wireless keyboard and wireless mouse will temporarily lose connection to your Mac. Make sure you have a wired keyboard and mouse available in order to continue using your Mac.
To reset your Mac’s Bluetooth module:
- Launch the Terminal app on your Mac.
- Copy and paste this command in Terminal and press Enter on your keyboard: sudo pkill bluetoothd
- You will be asked to enter your Mac’s login password. Simply type the correct password and press Enter to execute the command. Please note that for security reasons, when you enter the password in Terminal, you won’t get any visual confirmation.
See if your mouse lags or not after you reset your Mac’s Bluetooth module. If this issue persists, try the next fix, below.
Delete Apple Magic Mouse related Bluetooth property list files
If you’re using an Apple Magic Mouse, try deleting mouse-related Bluetooth property list files:
- Launch the Finder app.
- On your keyboard, press Shift ⇧ + Command (or Cmd) ⌘ + G to invoke the Go to Folder… prompt. Copy and paste the path and Press Enter to open the Preferences folder.
- Search “mouse” to locate the Apple Magic Mouse related .plist files and delete them.
- Restart your Mac and pair your Magic Mouse again.
See your Magic Mouse lags or not. Normally, after deleting the .plist files, the mouse lag issue should be fixed.
Short for Non-Volatile Random-Access Memory, NVRAM is a memory that saves its stored data like user preferences and settings on your Mac regardless if the power is on or off.
It’s rare for NVRAM to get corrupted on a Mac, but once it does, it may cause the mouse lag issues. Luckily, it’s quite easy to reset NVRAM on Mac, it just involves restarting your Mac and holding a certain keyboard key combination s it boots back up. Here’s how to do it:
Note: Depending on the processor your Mac is equipped with, the steps for resetting NVRAM will vary.
Reset NVRAM on Mac with Intel processor
If you’re using a Mac with Intel processor, just follow the steps below to reset NVRAM:
- Disconnect all USB peripherals like your external drive (except your external keyboard) from your Mac.
- Click the Apple icon on the top menu bar, then select Shut down… to completely shut your Mac down.
- After shutting down your Mac, locate the Command (⌘), Option, P, and R keys on your keyboard. We’ll use these keys later.
- Turn on your Mac using its power button.
- Press and hold the Command (⌘), Option, P, and R keys as you hear the first start-up sound and release the keys after the second start-up sound.
Reset NVRAM on Mac with the Apple T2 Security Chip

Running into the error message: “This build of Vanguard requires TPM version 2.0 and secure boot to be enabled in order to play”? If you’re going to run Valorant on your Windows 11 computers, you may get this error message. But don’t worry, this is not a critical error, and you should be able to resolve this problem on your own after following some simple steps!
What is Valorant TPM 2.0 error
According to @AntiCheatPD, Valorant has started to enforce both TPM and Secure boot if users are playing on Windows 11 to ensure a trusted platform when playing Valorant. If either of the features do not work, you’ll get the VAN9001 error message and Riot Vanguard, Riot Games’ custom game security software, will prevent Valorant from running on your Windows 11 computer.
How to fix Valorant TPM 2.0 error
To fix Valorant TPM 2.0 error, you just need to ensure both Secure Boot and TMP 2.0 are enabled on your Windows 11 computer. If you’re not sure if these two features are enabled or not, simply follow the steps below to check and enable it.
Check if Secure Boot is enabled
Secure Boot is a security standard developed by PC industry members to help ensure that a device boots using only software trusted by the original equipment manufacturer (OEM). If Secure Boot is disabled on your Windows 11 PC, you’ll run into the TPM 2.0 error in Valorant.
Just follow the steps below to check if Secure Boot is disabled on your computer:
- On your keyboard, press the Windows logo key and R at the same time to invoke the Run command box. Type msinfo32 and press Enter.
- In the System Information window, locate Secure Boot State in the System Summary section.
If the Secure Boot state is
Off, you’ll need to enable Secure Boot from the PC BIOS menu (UEFI Firmware Settings).
Check if TPM 2.0 is enabled
TPM 2.0, or Trusted Platform Module version 2.0, is an important building block for security-related features like Windows Hello for identify protection and BitLocker for data protection. TPM 2.0 is required to run Windows 11, and most PCs that have shipped in the last 5 years are capable of running TPM 2.0.
You can follow the steps below to check if TPM 2.0 is enabled on your computer:
- On your keyboard, press the Windows logo key and R at the same time to invoke the Run command box.
- Type tpm.msc and press Enter to open Trusted Platform Module Management window.
- If you see a message saying “The TPM is ready to use”, and its specification version is 2.0, it suggests that your computer has TPM 2.0.
- If you see a message saying “a compatible TPM cannot be found”, your computer may not have a TPM, or your PC may have a TPM that is disabled.
- If you see a message saying “The TPM is ready to use”, and its specification version is 2.0, it suggests that your computer has TPM 2.0.
Secure Boot and TPM 2.0 settings are managed via the UEFI BIOS (PC firmware) and vary based on your device.
Enable Secure Boot and TPM 2.0
There are generally two ways to enter the UEFI Firmware Settings. You can either restart your PC and press a certain key (usually F1, F2, F10, etc.) when you see your computer manufacturer logo screen or just follow the steps below:
- On your keyboard, press the Windows logo key and I to open Windows Settings. Then go to Windows Update > Advanced options > Recovery > Advanced startup. Click the Restart now button to restart.
- You’ll see the Choose an option screen. Go to Troubleshoot > Advanced options > UEFI Firmware Settings. Click the Restart button to restart to change UEFI Firmware settings.
- Once your computer restarted to UEFI Firmware settings, you need to find the Secure Boot option and enable it. The Secure Boot option is usually found in the Boot tab.
- The TPM 2.0 setting is often contained in a sub-menu in the UEFI BIOS labeled Advanced, Security, or Trusted Computing. The option to enable the TPM 2.0 may be labeled Security Device, TPM state, Security Device Support, AMD fTPM switch, AMD PSP fTPM, Intel PTT, or Intel Platform Trust Technology.
After you’ve enabled Secure Boot and TPM 2.0, the Valorant TPM 2.0 error should be resolved. If this error persists after you enabled both settings, you may need to downgrade your computer to Windows 10 to avoid the Valorant TPM 2.0 error.
