Aauugh!

The lights keeps flickering… The WiFi is often spotty and unreliable… And now my iMac is a zombie! Isn’t there anything working properly anymore ?!!

Ever since the last major OS update, the iMac started freezing now and then. Actually : almost every hour! So, I was suspecting a problem with Time Machine (it was freezing just as TM was about to start an incremental backup).

Then, yesterday night, out of the blue, the iMac started to freeze again every few minutes. It slowed down to a slow pace and all applications refused to start and giving a “this application is not responding” instead (well, Safari was painstakingly loading).

My computer is a late 2012 iMac, with a 21.5 inches screen, 2.9 GHz processor, 16 GB RAM, 1.12 TB Fusion Drive and it is running MacOS 10.13.3. I admit, it’s already more than five years old. Any suggestion to solve this problem?
