Ouch! Sorry to hear of your troubles. I’m waiting to update to iOS 8 for a month or two...
Getting ready to upgrade my Mac to 10.9, I feel it’s stable enough to run my Windows 7 via Parallels in.
Likely a winter project...
I’m a LONG way from updating to 10.10, maybe 2016...
Good luck!
Before I update, I would make sure the printers you have will support
the new mac software.
I had to call Apple support via Skype to report lost carrier signal
on iPhone 6 update 8.01
I wish I had read your post before I updated.
