PC STUFFIT EXPANDER ZIP FILE
I Quit Firefox, opened it up again and it seems fine.Ī few hours later I downloaded a couple of zip files from a legit site.I double-click on the zip file to extract the PDFs and I get a message that says: "Stuffit Expander.app will damage your computer. When I returned, Firefox seemed to hang, I clicked on links they did not work, I clicked on tabs, they did not change. Then, today, I clicked by user name, then Login Window, as I was leaving the computer for a while - and I had Firefox and a couple of other apps open. Yesterday, I tried a reinstall of the OS.

I tried to repair the OS using Command-R, but the issues would re-appear after a few hours of use. The first adds a pop-up calendar to the menu bar and the second allowed me to change the behaviour of the Home and End keys. The programs were both recommended by several websites: its圜al and Carbiner Elements. I had installed two programs just before all this happened, but removing them did not solve the issue.

Then I noticed things like emptying the trash would require a relaunch of finder to complete the process. It would simply hang, force quit would close it, but I would have to restart to even try to use it again. I did an upgrade, not a clean install.Įverything seemed to work fine for 2 to 3 weeks, and then I started having issues with Firefox. I decided to upgrade to Catalina (not sure why at this point).

I have a late 2013, 21.5" iMac that was running just fine with High Sierra.
