High Sierra Keeps Hanging !!!

There have been no previous reports of this kind of behavior with ClamXAV and High Sierra. You should report exactly what you are seeing to the ClamXAV Help Desk.

There is a known conflict that causes an "Error 13" under certain circumstances in ClamXAV that should be fixed by Apple with the release of macOS 10.13.2.

In the mean time, there is a new version of ClamXAV which is currently in testing and your issue might be resolved with that new version.

Go into ClamXAV's preferences -> Advanced, and turn on the option to "Enable beta ClamXAV updates" and click the OK button.

After that, select "Check for ClamXAV updates" from the ClamXAV menu.

When the new version has been installed successfully, go back into preferences and turn off the "beta updates" option.

Thanx a lot for the advice to erase all anti-virus-software. I deleted my beloved ClamXAV. Et Voilá the permanent crashes od Finder stopped. You saved my day ...

You learned nothing from my reply. Read it again. Having ignored it, your Mac may now be so hopelessly corrupted to the extent that it is likely to require completely erasing it, and rebuilding it from the ground up.

Rule 1 of Macs is don't install junk. Do not use non-Apple "anti-virus" junk, "cleaners", "doctors", "cleansers", "optimizers", "doctor cleaners", "cleaner doctors", or "doctor antivirus cleaners" on a Mac. They are scams.

If you already overlooked Rule 1, Rule 2 is to uninstall those things (credit dialabrain for number 2).

Rule 0 is to create a backup, so that you can recover from the corruption resulting from using garbage products that should never be installed on a Mac. To learn how to use Time Machine please read How to use Time Machine to back up or restore your Mac - Apple Support.

Since you didn't follow my earlier instructions though, I doubt you will follow these either. Good luck.

High Sierra doesn't work with JDK 9!

You can fix this by uninstalling JDK 9 by removing the correct folders and installing JDK 8 afterwards.

Check out this video for more info (links in description).

(ps: I don't own the video, it was the only solution I found on the web so I think it's worth to share)

"CleanMyMac" claims another victim.

To remove "Avast" use its uninstaller, which will remove it completely. Use no other technique, procedure, or product to remove it.

Recovering from the effects of having used garbage to "clean" a Mac will not be as simple.

If you're having trouble with high cpu usage for mdworker/mds/mdwrite processes, see this guide:

Follow John's instructions. You should not use any third party app that claims to clean, protect, etc. your computer.

I too have 2016 Retina MacBook 1.2 Ghz and 512 SSD. Did an erase and clean install H.S 10.13.0 Build 17A405 and no and no hangs.

Though, I do not use and have never used Avast Security nor CleanMyMac 3. They might be a partial cause of your issues but defer to more expert users like Dominic 23

An app can be "safe" yet still be 100% pure unadulterated garbage that should never be installed on any Mac. Get rid of it.

If you want to fix your problems then follow my instructions. So far you've done the opposite.

I quote what was written earlier "AV software is not required for macOS of any version."

The Apple Apps store is a good place to purchase software - yes but must realize even here you have to know what is required and what is not. AV software is NOT.

Mine is crashing often too... never has before. Disappointing to see Apple progressively going in the Microsoft direction where they dont test their software properly anymore. Windows is working like a dream.

Uninstall CleanMyMac3.
