First time asking for Mac OS help. Today i got a weird loading bar on my screen. This is actually the second time it happened.

Hi there There used to be a way to shut down the Mac just by pressing a certain key combo. I've just bought the new MacBook Pro (Apple M2 Max, 2023 running Ventura 13.4 and can't see to work out how to do it. This official instruction does not work (see screenshot) Is there a way to program a...

Hi all, my trusty 4,1 (flashed to 5,1) all of a sudden just shut down without being under load and wouldn't properly start up anymore. After it cooled off, it will boot again, but within 5 minutes or so before it just shuts down again. I read the threads about the temperature issues and cleaned...

I have a MacPro 5.1. I have Mojave installed, but am still using HighSierra most of the time. A few days ago I installed a new USB PCI card and swapped my old GTX 680 for a Radeon 580x. After the PCI card swaps, the only software I recall hastily installing –after receiving a notification– is...

Hi. Not so long ago I bought a Mac Pro 3.1. Found that he sometimes refuses to start if he stood off for more than an hour. In this case, it does not reach the sound of turning on and the Mac just turns off. The time from switching on to spontaneous switching off is different, but, as a rule...

Hello there, I’m having problems with my Macbook Pro. After using an external CD drive to burn music last week, it hasn’t allowed me to shut down or restart the computer.

My cMP 5,1 (flashed 4,1) running High Sierra does not fully shut down. The screen darkens but the cursor stays on. When the screen darkens, cursor jumps to upper left corner and remains live. If left alone, it seems system or monitor will sleep and awaken when mouse is moved. Just started...

I have a Macbook Pro with Touchbar 2017 model and I've noticed that when shutting down, all apps are quit, but then for a moment the whole screen instead of going black shows a "screenshot" of something that I was doing prior to shutdown. I can't say how long ago exactly, I haven't noticed but...

This doesn't happen frequently but it does happen often enough to ask about. If I leave my Macbook Pro on, closed, idle (and asleep) for a few hours or more sometimes I open it up to find that it has shut down. This happens even if the battery is at or close to 100%.

After I hit shut down, my screen turns black, but I still have full control of the mouse and the computer’s light remains on. I’ve tried waiting it out, but I’ve had to force shut down every time I’ve tried. I quit out of all my apps before shutting down. This only started recently; no idea what...

I normally fall asleep with my Macbook on, however after some time it sleeps automatically. When coming to use it the following day it wakes up as normal, battery is not drained. It functions for a few seconds, then freezes momentarily and shuts down. If I clip on the charging cable and leave it...

Hey, long term apple user and encountered first issue ever. My 10 months old iPhone 7 have started to randomly shut down and it can't be started again until plugged in to power. It doesn't matter the battery status, it happens even if its 100% and also even when it is actually plugged in. Also...
