• All very good, but you really don’t explain why it’s fast to b begin with then slows down. I have the same apps on my new computer as my four year old one and I’m spend more time watching that spinning ball on the new one which is only 4 months old.

  • Wipe my carefully manicured and cultivated and finely tuned workspace that has become a performance disaster?


    …Maybe you have a point.

  • Use “sudo purge” followed by your user account password in the Terminal app to clear your memory and any paging (virtual memory).

    If you boot from a SSD, consider getting a second drive and using it for downloads, documents, iTunes folder, Photos app library, etc..

    Memory compression works well, but if you’re low on RAM, take matters into your own hands and learn a few basic Terminal commands. That’s the best way to get to know macOS.

  • Rebuild directory with DiskWarrior and then and only then boot in safe mode until login screen (no need to log in). Then reboot normally.

  • Need a tip on getting Apple Mail to work in Sierra.
    The Web is full of complaints of Mail not working
    in Sierra and El Capitan. Thus I am sticking to Lion until I’m sure Mail will work in Sierra

    “Then reboot your Mac and hold down Command-R to boot into Recovery Mode. Your Mac will automatically load macOS Utilities (see image above) — select Disk Utility and use it to erase your Mac. Next, reboot again while holding down Command-R. This time, choose “Reinstall macOS” to get a fresh copy of macOS onto the Mac.”

    Why do you recommend booting into the Recovery partition, and then rebooting into it again to reinstall Mac OS?

    macOS can/should be reinstalled immediately after formatting the drive without needing to reboot.

  • “Keep apps and extensions to a bare minimum
    Those new Macs have one thing in common; they all come with just the standard Apple apps (Safari, Mail, Calendar, and the like) installed. Of course, it doesn’t take long for users to start installing their favorite apps, and each one of those apps is loaded with files and resources that are usually indexed by macOS. The more apps on your Mac, the more the operating system has to deal with and the more it slows down.”

    What? Indexing is done one time, and then doesn’t slow anything down. Unless an application is launched, it does not do anything except take up space on the hard drive. Just having an application on a Mac has nothing to do with slowing down the OS.

    And in my experience, mostly using older Macs (I transitioned earlier this year from a PowerBook G4 to a 2010 MacBookPro, which I upgraded to 16 GB memory, so I’m “modern”), even having a bunch of applications does not slow down your Mac if you have enough memory.

    This tip doesn’t make any sense.
