If you’re experiencing problems with file sharing not working in macOS Ventura, there is a fix to resolve the issue. This solution applies to SMB file sharing with macOS Ventura and devices connecting to or from the Mac, whether you’re experiencing connectivity failures, time outs, server unavailable, server may not exist, or other similar error messages.

• Open the "System Settings" on Mac from the  Apple menu
• Go to "General" and then to "Sharing"
• Find the switch for "File Sharing" and toggle it Off
• Restart the Mac by going to the  Apple menu and choosing Restart
• Upon reboot, return to the Sharing system settings panel and turn "File Sharing" back to the On position
• Resume file sharing as usual, it should work as expected

You may need to repeat this process after a few days, or at random, if file sharing suddenly stops working again between the macOS Ventura Mac and another Mac or device. Why you need to disable file sharing, reboot, then re-enable file sharing, is a bit of a mystery. Simply toggling file sharing off and on does not do the trick.

What causes the "macOS could not be installed on your computer" error? Several issues could cause the problem. However, the error screen should give you some idea of what's gone amiss. Here are some messages you might see underneath the warning:

• The path /System/Installation/Packages/OSInstall.mpkg appears to be missing or damaged
• An error occurred installing macOS
• Unable to unmount volume for repair
• Storage system verify or repair failed
• An error occurred while verifying firmware

Some of these offer more information than others, but they point to different stages of the installation that failed. The following steps and fixes should sort out any of the problems mentioned above.

Fixing this error may require some patience. It's best to start with the simple fixes, which often solve the problem, but if they don't, you have other options. Here are the approaches to try.

1. Restart and try the installation again. This may seem counterintuitive to redo the thing that didn't work, but sometimes a restart is all your Mac needs to sort itself out.

2. Check the Date & Time setting. If the displayed date and time don't match reality, this could be the problem. Restart your Mac again if necessary, then go to System Settings > Date & Time and enable "Set time and date automatically" setting. After this, try the installation again to see if it works.

3. Free up space. In some cases, macOS fails to install because there isn't enough room on the hard drive. To see how much is available, click the Apple logo and select About This Mac, click More Info, scroll down and click Storage Settings. You'll see a breakdown of what's living on your computer. If the available space seems low, move some nonessential files off temporarily to see if that lets the installation proceed.

4. Reset the NVRAM (https://support.apple.com/en-gb/HT204063). This tiny chunk of memory stores basic information such as the time, monitor resolution, and which disk to start up from. You may need to go back into System Settings to switch any settings this changed, but you can try the installation again before that to make sure the problem is resolved.

5. Restore from a backup. If you use Time Machine to regularly back up your Mac, you can go back to an earlier state using Recovery Mode to see if it's more compatible with the installer.

6. Run Disk First Aid (launch Disk Utility located in /Applications/Utilities). This may help if you're getting the "Unable to mount volume" error. First Aid checks the internal hard drive and makes any fixes it can. It may even be able to mount the volume after it's done. Then you can retry the installation.

If none of the above worked, it may be time to turn your computer over to the professionals.

Apple has increasingly made it hard to mess with macOS system files. That’s true whether you intentionally want to extend macOS’s functionality or if a malicious party is trying to install and activate a virus.

However, many system components and all Apple and third-party apps rely on preferences and other files to store your custom settings, caches for work in progress, and other data. If those files corrupt, macOS may be perfectly fine, but you can’t get anything done in an app or your account.

Once you’ve gone through troubleshooting your Mac within your account that doesn’t seem to improve matters, the next big leap before reinstalling macOS is to set up a fresh macOS user account. From this account, you can test hardware, like your Wi-Fi or ethernet adapter; add printers and scanners; or run third-party software that keeps crashing on launch.

Because a fresh account typically contains nothing that would already be corrupted, you can isolate whether a problem is in your everyday user account or a system-wide issue–maybe even hardware related.

Here’s how to set up a fresh, new user account in macOS Ventura:

• Go to System Settings > Users & Groups.

• Click the Add Account button.

• Enter your password if prompted.

Here’s how to set up a fresh, new user account in macOS Monterey and earlier versions of macOS:

• Go to System Preferences > Users & Groups.

• Click the lock icon and enter your administrator password.

• Click the + sign at the bottom-left corner of the user list.

Then, after those first three steps in any version of macOS:

• Choose whether to create a Standard or Administrator account. Give it a name, password, and hint, and click Create. When making the account, what kind should it be?

Create a Standard account if you want to test a problem from the perspective of a user without any extra privileges.

Create an Administrator if that’s your normal account type–that’s typical–and you’re trying to perform an apples-to-apples comparison.

• Choose  > Log Out [name].

• At the login screen, select the new account, enter the password, and click the arrow to log in.

Now you can check if your problem persists. For instance, if you can’t get a Wi-Fi adapter to show up in your regular account, this new one should have a fresh set of adapters that represent all the hardware your Mac recognizes. It should pull those into the System Preferences > Network pane (macOS Monterey or earlier) or System Settings > Network view (macOS Ventura). If Wi-Fi doesn’t show up as an adapter in the list, it’s likely a hardware problem, though reinstalling macOS is the next step before a repair shop just in case.

When you’ve debugged your problem, you can get rid of the account. You must be logged in using an Administrator account to do this. (Warning! These steps are irreversible. Choose “Don’t change the home folder” to retain it.)

In Ventura, go to System Settings > Users & Groups, click the i info button next to the account, click Delete Account, enter your administrator password, and click Unlock. Now select “Delete the home folder,” click Delete Account, and confirm.

In Monterey, go to System Preferences > Users & Groups, click the Lock icon to authenticate, select the account you create to debug macOS, click the – sign at the bottom-left corner, choose “Delete the home folder,” click Delete User, and confirm.

If you encounter the “USB Accessories Disabled” error message, try the troubleshooting tips below to resolve the problem.

Disconnect & Reconnect USB Devices

• Disconnect all USB devices from the Mac, then plug them back in again and see if the problem goes away.

• If you aren’t sure which device is causing the problem, try disconnecting USB devices one at a time to see if the error message goes away.

• Prioritize whatever USB-C devices may be drawing the most power, for example trying to use an external GPU through a USB-C hub may often trigger the problem.

Troubleshooting USB Hubs

• If the USB hub is powered, be sure that it is connected to power directly.

• If you’re using a USB-C hub, try plugging it into a different port on the Mac

• Try disconnecting the most power-hungry device from the USB-C hub, and instead plugging that device directly into the computer instead using one of the built-in USB ports on the Mac.

• Try using a different USB-C hub.

Miscellaneous Troubleshooting Tips

• Connect the device directly to a different USB port on the Mac.

• Reboot the Mac with the devices connected.

• If you’re concurrently experiencing display issues with an M1 Mac, try connecting the display directly to the Mac USB port and use other devices through the USB hub (if applicable).

If you’re experiencing this error on an Intel Mac, sometimes resetting the SMC can resolve problems with USB as well. If you’re experiencing the USB Accessories Disabled error on an Apple Silicon Mac with an M-series chip, there is no SMC to reset so simply rebooting and using the troubleshooting steps above is typically enough to resolve the problem.

If you’re still experiencing power issues and USB accessories and devices not working on the Mac, it’s always possible there is a hardware issue that can only be resolved through official Apple Support, so if the above tricks failed reaching out directly to Apple Support is a reasonable next step.

Apple ID Recovery Key serves as an additional way of authenticating your Apple account, and it can be used if you forget your password and lose access to another trusted device. Using a recovery key eliminates the need to visit Apple’s website to jump through hoops like verifying payment method details and answering security questions for a password reset. The ability to generate a recovery key from the Mac requires macOS Big Sur or macOS Monterey.

If you have a Mac, it’s pretty easy to generate and use a recovery key.

• Open “System Preferences” on the Mac (from  Apple menu or Dock).

• This will open a new window on your Mac. Click on the Apple ID option located at the top-right corner.

• Now, click on “Password & Security” from the left pane. In this section, you’ll find the Recovery Key option below Trusted phone numbers. Click on “Turn on” next to the Recovery key option to continue.

• When you’re prompted to confirm your action, click on “Use recovery key” to proceed.

• Next, you’ll be asked to enter your Mac user password. Type in the password and click “OK”.

• If you have an iPhone, you’ll also be prompted the enter the passcode you use to unlock your iPhone.

• Now, your unique recovery key will be shown to you on the screen. Make sure to write it down in a safe place that you’re able to easily access. Once you’re done, click on “Continue”.

• Next, you’ll be asked to enter your 28-character recovery key to verify that you’ve noted it down. Click on “Done” after typing it in.

• The feature is now turned on. If you want to change the recovery key for any reason, you can click on “Create new key”. You also have the option to turn this feature off at any time.

From now on, you’ll have just two ways to reset the password for your Apple account. You can either reset the password from a device that you’re already logged into, whether it’s your Mac, iPhone, or iPad, or you can use the recovery key instead. The latter could prove to be invaluable if you don’t have access to another trusted device, or if you only have one Apple device.

Note that when you disable and re-enable the Recovery Key feature, a completely new key will be generated for your account. If you lost your current recovery key somehow, you can replace the key with a new one on your Mac from the same menu using the “Create new key” option.
