With my iPhone 8 Plus, since my last iOS update I experience popping and clicking during calls, audio fades out, poor quality under any condition, apps freeze, phone won’t answer when swiped. Emails disappear then reappear, Bluetooth syncing issues.
Please don’t try to diagnose these issues, I’ve had the phone replaced once already. Multiple restores and resets. None of this happened until my last iOS update.
With high Sierra macOS on my 2014 mini, the issues are endless. Browser issues, display issues, Preview is pretty much worthless to me now. Font issues, cut and paste issues, email issues, software compatibility issues, sync issues between devices, time machine backups work then don’t work, ... I can go on.
All affecting, delaying, or preventing me from making my deadlines.
I depend on my devices being synced up and working. I work from home and in the field. I do research, cut and paste a lot of stuff, lots of texting, emails, and calls.
The most disappointing issue I have is using Preview to edit PDFs. With high Sierra I’ve had nothing but problems. Using Preview was one of the reasons I’ve stayed with a Mac for so long.
I’ve burned up more than one work day doing fresh installs, restores, and/or looking for alternative software.
