high sierra

I’m on a Mac Pro 5,1 and freshly installed High Sierra. For some reason I can’t open ANY application downloaded from the AppStore. Sometimes I can’t even download the app, sometimes it allows me to at least download it after I try it over and over again. Some people I already asked suggested...

I’ve successfully upgraded the firmware on my 4,1 Mac Pro to a 5,1 (now officially running High Sierra). Everything worked perfectly fine until I enabled SIP again. Now everything runs painfully slow, just opening Launchpad for example takes what feels like ages. Also, if I want to open apps...

Thought I'd pop in and ask a 2 part question here about unsupported versions of OS X/macOS being hacked onto an Early 2008 iMac [8,1]... So... 1. Is Sierra or High Sierra the highest unsupported OS that can be loaded onto such a beast? and 2. Is RAM still stuck at 6GB reliably? The last...

It's been ages since I've been on here but I'm at a loss of how to proceed outside of hiring a data recovery specialist company... My Dad has an 4K Retina 2017 [18,2] model that was purchased online through the Apple Store. It's been a champ up until about a month ago when an OS update...

Hi all, I've downloaded the latest security update from the Mac App Store. It's update 2020-004. My MacBook Pro is running on High Sierra (10.13.6). When I try restarting my computer to install the update, it gets stuck during the shut down process on a black screen with just a movable cursor...

I need some help! I have a Late 2011 MacBook Pro. The other day I turned it on, plugged it into my 2nd monitor and it got to the password screen. The 2nd monitor then turned orange and the MacBook had these green lines appear. I tried to reboot. In regular boot it gets about 1/4 of the way...

It's the last supported OS and it's currently quite happy on Sierra 10.12.6. It's got a spinning 1TB HDD and core i5, should I just leave it on Sierra or should I upgrade to HS? TIA :)

Have a 2013 and an Early 2015 13" 2.2 GHz Intel Core i7 8GB RAM MacBook Air running High Sierra. Considering upgrading and wondering how much slower the machines will become.

Hi there, I hope you and your loved ones being safe and happy. Yeah! really paranormal! ?? Last night I noticed that my MacBook (Mid 2010) act unusual, background audio/video suddenly going fast back/forward (mostly back or skip to another tracks) while I taking note or browsing web, MacBook...

I wonder what are the major benefits of upgrading Mac Pro 5.1 to Mojave from High Sierra? Also any problems once updated to Mojave? as I read that problems will happen with Bluetooth and Wifi and Airdrop...

Hi Everyone, So i've been having an issue with my Mac pro for over a year now. I've tried a few different things to fix it and still can't seem to find out whats wrong. I'll be working and suddenly the screen starts to glitch with lots of random pixels (please see attached images). Then all I...

I have macOS El Capitan on my Mac Pro and I am trying to update my Mac Pro to macOS High Sierra so I can update it to Mojave later since Mojave requires to have at least macOS High Sierra. But when I run the installer I get the below error. Any advice on the steps needed to overcome this issue...

Hi guys, I have a problem to which I don't find any solution. Spotlight is not showing any finder folders anymore. Rebuilding the index, meddling with the spotlight privacy settings, or any first page google suggestions did not work. Curiously, finder folders on an external hard drive do show...

An elderly friend has a 2010 iMac 21.5" working on High Sierra. Lots ofRAM and 1Tb SSD Recently he had had huge problems accessing folders and other data. It turns out that, for months, he has not been able to shut down properly and can only do so with forced shut down i.e. power on button held...

Hello everyone, I would like to know how to transfer (downgrade) the bluetooth module from Sierra to High Sierra. On my iMac 2011, equipped with a bluetooth 4 dongle, I have three partitions: one with Sierra, one with High Sierra and one with Catalina (patch). There is no way or program to...

I just upgraded a 2009 Mac Mini 3,1 to High Sierra. The first thing I did was to take the original Hard Drive and using a cloning appliance I cloned the old MacOs HD (120GB) onto a 250GB SSD I had laying around. Unfortunately, that created a 120GB partition with the OS and a 130GB "Free Space"...

I have just revived an old 2009 Mac Mini (3,1) with High Sierra. it went from essentially a high tech paperweight to a pretty useful machine in less than an hour. I am thrilled. The SSD alone speeds up things dramatically and I am looking to upgrade the RAM (currently 3GB for some reason). I...
