I waited for version 10.13.1 and installed this one on an older mac (iMac mid 2011 with an AMD Radeon and SSD).
Initially I had a lot of freeze problems: this was mostly the colored wheel after the mac went into idle mode and had to resume, with after a while also the mouse movement totally blocked and with no other choice than the hard reboot...
Today my system seems much more stable.
I cannot really explain this but I think that certain actions triggered a few corrections to certain configuration data and perhaps also some access rights (probably similar to what certain people did via the Onyx tool):
- I opened the console view and looked for errors in the logs, this gave some hints... in my case regarding iCloud & access issues
- I activated the option to share the mac & cloud analysis with Apple in the security & privacy settings
- I booted twice in safe boot mode (https://support.apple.com/en-us/HT201262)
- I reconnected each user again to iCloud.
- I adapted the sleep time from 10min to 30min for both the computer and the display (not sure this really helped..)
- I forced my Norton Security to get updated
- I had printer/scanner drivers that were quite old but supported by the macOS itself - I removed them all, selected them again forcing fresh driver installs
- I did a manual check of the SSD that was converted from HFS+ to APFS (though no errors reported)
- I let my time machine do some backups
- I went into Photos to force the rebuilds of the libraries
- And since then I boot again in normal mode
The above does not guarantee of course it works for other people but in my case it did 😝 🙂.
My Time Machine is now still trying to make a non-logical giant backup that does not make sense for me but that's perhaps because of the total rebuild of the Photos library ...😟
