    Solution: Reclaim storage back from "System"

    After upgrading to High Sierra the "System" storage was 260GB (About This Mac -> Storage). I also used DaisyDisk to confirm that there were "200GB of hidden system files" that can't be shown or deleted. Turned to our good friend Google and I found that Time Machine local backups were the...

    WiFi performance issues on 2015 MacBook

    Hi Anyone else had any WiFi slow down issues on High Sierra? I'm running the GM and using Safari. I notice horrible slow downs when trying to search the web or load a web page, so I rebooted and ran a speed test. I got about 38Mbit down and 7Mbit up, compared to 43Mbit down and 9Mbit up on my...

    Preview App Changed in High Sierra

    I noticed some changes in the app, most of which are towards the positive side. Has anyone found that "right-click" no longer holds the option of highlighting with colors? This creates some inconvenience for me since mine is without touch bar... Can we change it back?

    iMac (late 2009) with Samsung 840 SSD & High Sierra

    Hi guys, I've been running a late 2009 27" iMac with a Samsung 840 SSD (replacing the SuperDrive) on Sierra. I've had persistent problems for a while booting up to the 'prohibitory' symbol. Usually a second or third restart eventually boots successfully. Running Disk Utility reports no errors...

    Dock not auto-hiding

    I cannot get my dock (which usually stays hidden at the bottom of my screen) to appear when I move my cursor to the bottom of the screen since I have updated to High Sierra. I have tried to quit and restart, remove/uninstall plug-ins (only one - cdock, plus I also re-enabled SIP), and even...

    Safari

    Why would Apple include a check box in IOS11 to block Camera & Microphone access in Safari but not offer the same feature on High Sierra? Does Tim like Mark's tape trick on his MBP?

    10.13: Convert HDD from HFS+ to APFS

    Greetings! How do you convert an HDD over to APFS after upgrade? I have a single, standard SATA hard drive in my 2011 MBPro, and of course the in-place upgrade to High Sierra did not auto-convert it over to APFS. I went to Disk Utility, but the "Convert to APFS" was grayed-out (unusable). I...

    What Happened To Hardware Acceleration in High Sierra?

    I read in some threads that VLC already supports hardware decode. Even a VLC developer said this. To me and to my specific usage, VLC is pure horses**t. It's the worst player being intensive resource hog that doesn't seem to think about battery at all. I found IINA and have been using it since...

My understanding is that the upgrade will change the file system from HFS+ to AFPS. I also use a late 2015 iMac, with a fusion drive. The upgrade does not...
