I have recently upgraded from Mavericks to Sierra. Before the upgrade I turned off TimeMachine. Can I just turn it back on now or should I start over by erasing the drive and letting TimeMachine start fresh?

I just noticed that there is a hidden .Trash folder at the root level of my hard drive which contains a few files from 2014. Why does this folder exist and how did the files get there? I understand that the normal .Trash folder is in the user's home directory.

I finally replaced my old MacBook Pro Late 2008 with a 5K iMac 2017. I had added additional RAM and replaced the HDD with a 1 TB Samsung Evo 840 SSD. But, actually, I was not using the old MBP very often in the last two years. I decided to start the new iMac with its clean pre-installed MacOS...

Hello - I purchased a 2014 Mac Mini. I took it apart a few days ago to install a SSD. Everything seemed to go well. I installed the OS via WiFi and then upgraded to Sierra the same day. The WiFi worked fine the first couple days, but then today I went to put some files on the external drive...

Hello. Yesterday I decided to update to Sierra from El Capitan on both the disks on my Macbook Pro (mid 2012); the update on my SSD went without a hitch so I decided I'd update my other disk, too. I downloaded the .app and the installation started as normal; once it got to the point where I'd...
