What has been your experience with 10.13.4 update on Legacy Macs
I believe evil corporate Apple has done it again.
In the last month I have gotten in five 2012 and earlier MacBook Pros and iMacs that all had the same problem. After the 10.13.4 update they all slowed down to about 10% of the speed they had before. Theses are all machines that I have upgraded the hard drives on with Seagate SSHDs. These machines were driving me up the wall. 3/4 of the time the machines had done incomplete updates. On these, after a lot of effort I got the updates completed. After doing everything I knew to do, I tried booting from an external with a lower system and BINGO! everything was working fine again. I wiped the drives and installed a lower system and all have recovered.
My personal belief is that Apple has intentionally put something in that update to detect non-Apple drives and bring these machines down. These are now legacy machines (over six years old) and Apple refuses to work on them. So if you take it to them . all they will do is try to sell you a new machine. Time for a good class action law suit!
Has anyone else experienced this issue?
