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.
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. Kill it like this.
kill -9 91475
Now clear the ...
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.
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 ...
Yes, there are some terminal commands to set your default setting to "none".

Posting my findings here since I sunk some time into this issue recently:
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 ...
In my case it did work after running this in the Terminal
(I am using a USB-C monitor for powering the MacBook Pro)

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.
First of all, this partition is incredibly useful if you accidentally destroy your MacBook somehow, for example deleting your MacOS. It allows ...

Go to Settings -> Network -> Advanced -> DNS. Then make literally any changes at all to DNS (reorder your DNS entries, for example). Then click "Ok" followed by "Apply" on the next screen. Don't be fooled into thinking that the particular change you made was significant; it's the magic of the "Apply" button.

Open System Information app before you plug in your hub.
Navigate to "USB" in the list and click.

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 ...
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.
I fixed the crash, the problem seems to be caused by a problem in the kext of the Thunderbolt port.
Steps to fix it:
reboot with CMD+R pressed.
sudo csrutil disable
reboot in normal mode
sudo mv /System/Library/Extensions/AppleThunderboltNHI.kext /System/Library/Extensions/AppleThunderboltNHI.kext.BAK
reboot with CMD+R pressed
Here's a simple fix to this design flaw. Whoever thought of ending the ground circuit at the pin on the transformer, where it connects to the plastic channel on the UK plug adapter needs to be sent on a long holiday. I finally got my Trackpad working (while the charger's plugged into the computer), by ensuring continuity between the transformer's earth pin ...
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. Many broken Macs still work to this extent and since you didn't mention how it was broken, it's quick and easy if power and the storage controller work minimally.
From there, you can copy / ...

Sure. It’s a fabulous CPU, blazing fast storage and faster than most Macs a year old in terms of all the benchmarks you’ll need for getting started developing.
Great value and it holds resale value much better than more pricey Macs. Unless you have a great value used Mac, get this and work the heck out of it. Assuming you ever find it’s slowing you down, ...
i justed dived in and bought the display and it works without any adapters.
It came with a mini displayport cable witch is compatible with thunderbolt 2 port on MBP right out of the box, no issues.

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).
If this doesn't work out you might want to look at making a bootable USB ...
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).
In order to repair a Mac you will (generally) need an administrative password as doing things like reinstalling software and the like requires an admin password.
Even if you create a separate admin account for this person to use in effecting repairs an unscrupulous person would have no trouble getting into your stuff.

The battery status of Poor indicates that something isn’t lining up in how the measurement circuit sees the voltage profile change.

This is not normal. There are other people having similar issues.
Many suggest that it is related to:

the pressure on the LCD screen when putting the MacBook Pro in a bagpack
Is this something that comes preinstalled in a MacBook?
No. It is a 3rd party app.
Is it okay to completely remove it?
Yes, it is okay to remove it if you don't use it. It must have been installed by the previous owner.
If this MacBook is a shared computer and it's possible that some other user may be using the app, it's safe to leave it.
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. This is supported by both monitors.
When you pick 1920x1080 Lightning, in actual fact a 3840 x 2160 resolution signal is generated and sent to the monitor. This consists of ...
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.
Download the binary from the "releases" section, and extract it if necessary. Then from Terminal.app, cd to the directory the displaymode file is in. With any secondary displays ...
You should be fine. The service is available globally and can be availed by walking into any of the nearest authorized service provider in your city/state. The /in/ subsection is not available on Apple's homepage because Apple doesn't yet have an online store/retail store in India.
