Hello, I have been experiencing crashes on my 2020 iMac 27" with AMD Radeon Pro 5500 XT 8 Gb for the last few weeks, randomly, sometimes multiple times a day and some other times no crashes at all for a few days. I was told to start in safe mode, also to reinstall macos (it even crashed during...

Hi Macrumors! I am a long time macOS user and have encountered something I never saw before. I am using two external WesternDigital Drives since 2 years. One is a myBook and one a myBook Duo. They are connected with USB. Everything worked flawlessly. I used CarbonCopyCloner to automatically...

Hello, I've been having problems with my MacBook Pro (late 2019, 16 Inches). Even when I do "non-demanding" tasks and I'm connected to connected to my external display (for example: split external display and Mac display with a YouTube video) the temperature rises suddenly by about 10 degrees...

Hi guys, for a few weeks now my macbook crashes almost every time I put it to sleep and don't wake it up for a while. I've attached the crash report, but can't really make sense of it :( Can anyone help me with this? Thank you!

Got a 16" M1 Max around mid-December. Didn't have a problem for the first week or so, then the unit began to panic constantly, no matter what I was doing (watching videos, on the phone, on Discord...). After around 20 panics in around 2 weeks, I brought the computer into Apple, who thought it...

I'd like to create this guide for those of you who find themselves in a situation similar to mine. I have a Mid-2014 15" 2.5GHz MBP with the GT750M. It was salvaged from a reseller on FB who said it had graphics issues. It turns out that a lot of sensors in the Motherboard for some reason read...

For some reason when I wake my Mac from sleep the screen is black and none of the buttons work. Eventually, I get to the "your computer has restarted because of a problem" then I press any key to resume startup. Does anybody know why this might be happening? I have a link to the log here...

Mac expert sleuths needed. I have a 2017 27" iMac with 24g RAM and 2tb fusion drive. The latest OS is installed, which is 11.5. About once or twice a year for three to four days, this machine slows down to the point it becomes unusable. Activity Monitor constantly shows high kernel_task...

Had a couple of panics in the last few days on my M1 Mac Mini after a couple of months before that of smooth sailing, trying to figure out the problem. Here's the panic string from the most recent occurence: "panicString" : "panic(cpu 0 caller 0xfffffe003196fe28): DCP DATA ABORT...

Hi everyone! This is the thing... MacBook Pro (Retina, 15-inch, Mid 2014) Multiple Partitions (macOS Mavericks, macOS Catalina, Windows 10, Linux) My SSD disk has a pure GUID partition map, al operative systems are installed in pure EFI mode. No MBR. Everything worked fine until I updated...

Hi, Was just wondering if anyone else with an iMac 2012 27" has issues running Chess at full screen, max resolution. It's weird -- it will run perfectly fine on El Capitan, and on Mojave however I have issues running it on High Sierra without it crashing + kernel related to the GPU. Happens...

I upgraded to Mojave a few weeks ago and it was fine for a bit. Now I'm having a big issue with wifi. After a few minutes of use, kernel_task will random shoot up past 100% CPU (sometimes nearing 200%), majorly lag the whole system, and disconnect from wifi. When I click to reconnect to wifi I...

Hey all, thank you so much for any help in advance. Looking for some troubleshooting help for one of our rigs. We have been updating to 10.14.5 Mojave on multiple machines (from High Sierra 10.13.6), and have encountered many crashes with a late 2013 Mac Pro. Our other Mac Pros, also late 2013...

What has everyone seen at the kernel level that's new? Apple has forgotten for a long time (according to various Apple "core OS" engineer buddies) that the kernel and core OS innovations are important. We're at a point now where Linux (kernel) has surpassed Apple in this area (as of about 10...

Hello I am trying to figure out what programs I can "shut down" and get rid of when the Mac starts up. I realised at times the Mac obviously takes longer to start which is due to a lot of stuff starting up. I am reinstalling in the next few days a complete new OS on the system and removing...

Hi everyone Im having a problem with my MBP. Every time it goes to sleep being by closing the lid or just putting it to sleep manually the computer crashes and i need to restart it. I have discovered that it only happens when the Wifi is On, if I turn it off everything works fine. I have all...

Hi everyone, I'm new to the macOS world, and recently I've been getting a kernel panic which basically happens when I let my Macbook sleep for more than 5-6 hours. This is the message that I keep getting : *** Panic Report *** panic(cpu 0 caller 0xffffff7f9270f341): "Failed to quiesce...

Getting a lot of kernel panics with my nMP, resulting in system freeze followed by black screen, restart and "Your computer was restarted...." error message. Problems seem to occur when pushing the system, rendering video etc. Extensive hardware tests for 80 hours at our local ceritified...
