Whereas Disk Utility can perform cursory disk integrity verification checks and equally cursory repairs, it's inadequate to draw a definitive conclusion regarding disk failures. Unfortunately that's the best EtreCheck and Disk Utility can do. if I were to buy a new computer should I rather opt for an iMac or a Macbook.Is it worthwhile to buy a new HD and/or RAM and DIY it into the computer?.should I perhaps uninstall Catalina and go back to High Sierra?.

is there anything more I can do to get the computer run at a normal speed?.

In conclusion my questions are the following: But the OS proprietary Disk Utility says that the HD is good. I used Etrecheck which concluded that I might have a damaged HD.

archived most emails (each mailbox contains < 500 emails).

rebuilt all mailboxes (3, iCloud, Google, AOL) many times,.

If I use the option 'Export as PDF' a window appears, 'Exporting content to PDF' and remains there for 3-5 minutes before the PDF file of the email is created.

If I click on a (HTML) email in the preview window it takes 15-20 seconds for it to display in the preview window.

If I write a new email, I type a sentence, and then see it slowly appear in the email window, letter by letter.

eliminated all third party software with the exception of a printer driver (Canon) and a driver software for a connection to an external server (Synology Drive)Įspecially Apple Mail is inconceivably slow.

I have a similar problem to niandralades76's.Īnd ever since I upgraded to Catalina (10.15.4 (19E287) the computer runs incredibly slow.

And first of all, thanks for your many insightful answers to really hard problems concerning MacBooks, iMacs and iOS.
