    Sundry questions about time machine's "versions".

    1) Does time machine delete the oldest versions based on their age, or the number of versions created? 2) If it deletes based on age, how old do the versions have to be to get deleted? 3) If it deletes based on the number of versions created, how many versions do there have to be before the...

    So I got a 15" macbook pro from mid 2010 that still runs snow leopard, and I am absolutely amazed about how nicely it's been running for all these years.

    Sick of the beach ball

    I have a 2014 21" iMac. I use hardly any space on the hard drive. So I am getting a bit tired of the 'spinning beach ball' every few seconds. Deleting PLIST files, PRAM resets, file cleaning, memory cleaning, dicking around with WiFi channels and doing a f**king rain dance to the king of the...

    Hello, Since upgrading to Sierra, I thought I noticed some severe battery drain. My macbook Pro went from fully charged to 5% in about two hours, while only using Pages. Yesterday, I forgot to bring my charger, and started freaking out while I was still typing because I only had 5% battery...
