Updated iMacs to OSX 10.13.3.... like wading through Treacle !!.... Solution c/o Apple Care

A few days ago I updated a couple of iMacs from OSX 10.13.2 to 10.13.3

Afterwards they were so slow at some Apple related jobs, it's like wading through Treacle.

 

Empty Trash took 20+ seconds, similar for screen grabs to appear.

 

After a couple of days getting nowhere, I contacted Apple Support.

They rang back, so a free phone call, considering any contact takes ages, as they take you through everything.

 

We tried various things, to no avail, SMC & PRAM reset etc

 

Starting to think I may have to re-install OSX from scratch, from Time Machine, and potentially lose 4 days work.

 

A Supervisor was called in, they sorted the problem  within a few minutes.

 

 

 

 

 

 

 

 

 

 

 

 

 

She said to remove (uninstall) any Virus protection, I had ClamXAV and Sophos installed.

She said Apple built in firewall was all I needed, and is regularly updated.

 

 

 

 

Now for the final piece of the jigsaw....

 

She said to instal Malwarebytes for mac, which I did.

A full scan, which only took a couple of minutes, showed some malware & popups hidden away.

 

 

 

 

Offending items deleted.

 

 

 

 

 

 

Voilà

.... iMacs now back up to speed, with empty trash & Screen grabs appearing instantly.

Must be a good firewall, then.

Gatekeeper & Xprotect are an integral part of Apple OSX.
