Is this a firmware update or is something amiss?
Every time I turn on my recently-updated-to-Yosemite Mac mini it shows a screen akin to what happens when you update an iOS device. Is this normal? I’m new to a Mac, although I’m familiar with iOS devices. My mini has a 2.5 GHz Intel Core i5 processor with 8GB of RAM and it’s slow, despite having 445.72GB out of 500GB free… Brian Anderson The loading bar at boot time is normal. Yosemite introduced this instead of the spinner that we had before, to give you an idea of loading progress. Progress bars don’t advance at an even pace; it’s only a rough guide. Your Mac mini is the same spec as mine, and I’ve noticed that Yosemite is slower to boot up than Mavericks, but once I’m logged in, things run at the same speed. That 445GB of free disk space has no effect; disk space only affects how much room you have to install apps and save stuff. It won’t slow your Mac down until you’re out of space. The speed of the disk drive does have an effect on how zippy OS X feels, though. If you upgrade your internal hard disk to a SSD, such as the MX100 (£167 from crucial. com) you’ll see a performance boost.
