This is a common problem with Macs, but it's usually easy to fix. You probably just need to reset your System Management Controller (SMC), which controls things like how your computer sleeps/wakes and responds to opening the lid from sleep, etc. If this does not work, you could go a step further and reset your Nonvolatile Random- Access Memory (NVRAM) and/or ...

Generally: if the hardware fits, you can swap it. Installations of MacOS are usually device-independent. You could put the hard drive from your Mac into an external drive caddy and boot up from it on most Macs. (As long as the Mac model isn't too old to run the OS.) The exceptions are when a new model is released with a unique OS build version containing ...

You could put the old HDD in the new machine. Buy a HDD caddy off ebay (or aliexpress or so) and replace the DVD-ROM with it. Nice solution for extra storage. And if you ned the option for an optical drive, buy an external DVD-ROM.

What I ended up doing is to put a Screen Saver item to my TouchBar and configured the system in Security & Privacy to require a password after a short period of time.

That's the screen for a firmware password. An Apple Store or Apple Authorized Service Provider can remove it for you assuming the machine is newer than 2011 and you can prove ownership. Other than that, there are a few low probability solutions you can try yourself: Internet Recovery Mode by holding Option-Command-R or Shift-Option-Command-R at startup. ...

Try the following steps to fix this. Open the terminal and type the following: ps aux | grep QuickLookUIS You will see something similar to this output: username 91475 0.0 200.0 4353832 59964 s005 S+ 5:45AM 0:01.78 QuickLookUIS The number after your username is the process id.

Yeah, that pattern looks like uninitialized video memory. That kind of thing happens when the machine comes out of sleep incorrectly or if there is a GPU memory pin that is coming loose. I say that because it’s a regular pattern. Regardless, if it’s under warranty, be sure that Apple has noted that you reported a problem. Better safe than sorry.

It may be just a freak occurrence. If it happens again, you should bring it to an Apple store. Is it under warranty? If it is, be sure to get it checked out and have the issue on file before the warranty expires.

I suggest booting into diagnostic mode (search here or Google for instructions based on your particular Mac). Either it’s a fluke or your GPU is soon to die.

If the machine is attached to an iCloud account, you can wipe the machine. I think you will need to go to an Apple store with the original owner or proof of ownership. Don’t whine about it. This is a feature that keeps stolen Mac’s from becoming a thing. With Catalina, the original user will even be able to track the location of a stolen device, even if it’...

Unfortunately the defaults write method does not seem to be reliable anymore. The most reliable way I've found to do this is with AppleScript. The downside is that it can take 15-30 seconds to run, during which time you should not do anything else with your keyboard or mouse. The good news is that you should be able to save the AppleScript below as an app ...

Posting my findings here since I sunk some time into this issue recently: Problem I was seeing icdd eat up large amounts of memory (7-8GB) and around 100% CPU on my macOS (version: High Sierra - 10.13.6). However, I was able to identify that the issue only occurred when my Wi-Fi was on. Terminating the icdd process didn't fix the issue, since the problem ...

First of all, this recovery partition usually takes less than a gigabyte of storage, as researched online and in my early 2014 MacBook Air. You may want to look more into why your Recovery HD partition is that large.

Open System Information app before you plug in your hub. Navigate to "USB" in the list and click. Note which information isn’t about the device you’re about to test. Then plug in the hub and refresh the window contents. Here is an example of mine. You can see it is identified as USB 3.0 capable, speed up to 5Gb/sec:

Did you check your system preferences (Apple menu -> System preferences -> Sound)? There you have three panels. Check the one for "input" and select the external microphone. Now it would be helpful to know whether your mic uses the USB port. In that case it seems that during enumeration it reveals itself to your Mac as a speaker. Please make sure you load ...

Looks like the anti-glare coating on your MacBook's screen is damaged. You should take it back to the store and ask for service or the anti-glare coating replacement.

I was having this problem with my 15-inch 2018 MBP running 10.14.4 and 27-inch late-2012 iMac running 10.14.5. Doing a whole bunch of stuff on the iMac (resetting SMC, NVRAM, changing brightness levels) didn't fix it. But resetting the SMC on the MBP did fix it for me.

Here's a simple fix to this design flaw.

i was facing the same issue, added the root cause of my problem was system overload due to an application launching with every boot - for me the issue resolved with having to wait for about 30 minutes after black screen appears and letting the CPU takes it's time to load - then exiting the application.

Welcome @user65526! So, generally speaking, more information is needed for something like this. The closest I can guess is: some kernel extension, possible related to a graphics card or external video display (?) is getting hung up with Apple's "Power Nap" feature, also known as darkwake[s]. I'd recommended disabling the feature entirely, by entering in ...

If it is a 2013-2015 MacBook Pro, you can open it and take the SSD stick out quite easily, and put in any 2013-2015 MacBook Pro or Air (yes the internal SSD connector is the same for all of those models) and access it there, either by booting from it (assuming the MBP/A you put it in has new enough firmware to support booting from the version of macOS on the ...

This has been answered for 'the other way round': putting a Retina screen in an older MBP, and I'd suggest many of the answers there apply here. The screens are different dimensions, and use different connectors. The firmware expects the original screen resolution.

The easy operation is to Use target disk mode to present your Mac as a pure storage device and connect it to another computer.

Based on your post, your MacBook should be compatible with the Mojave update. Once the App Store app finishes downloading and installing you should see a installer in the Launchpad (it should automatically open, otherwise try double clicking on it to manually start the installer).

The amplifier to make sound is the likely cause of failure. Since that’s on the logic board, a free warranty swap or a flat rate repair for $300 or so are the likely costs to fix this properly. Have you tested installing a new OS on an external drive or wiping and reinstalling in case it’s software? That’s worth doing so you have a backup or confidence you ...

You won't need any separate cable to connect the display to your 2015 MacBook Pro. A Mini DisplayPort cable is attached to the display which can be plugged into one of 2 Thunderbolt 2 ports present on the left side of your MacBook Pro (besides MagSafe 2 connector).

The lighting bolt icon indicates that it is a Retina (HiDPI) resolution. Essentially when you're picking 1920x1080, a 1920x1080 resolution signal is generated and sent to the monitor.

The built-in display should have a native resolution of 2560x1600. So it should support 1920x1200 @1.3x. You can use the displaymode command line tool to change the resolution.
