The only thing that worked for me was resetting SMC (System Management Controller). Press SHIFT OPT CTRL and the Power Button at the same time. For more detail read here.

I got it fixed by inserting a needle in the case’s holes right underneath the lid. Keep pushing it up whole holding the lid with a slight press, repeat the process and keep switching the holes all the way up!

For anyone wondering about this in 2019 (this old discussion is the first thing that comes up on a Google search when looking for "mid-2009 Macbook memory upgrade, maximum, 8gb, 16gb" or some combo thereof), no, you can't get your 2009 Macbook Pro to recognize more than 8gb of memory -- and no, there's not a magic act of "tricking" your Macbook into booting ...

No as it won’t have shipped with it. It won’t boot to alternate installers so only recovery options to install. So only Catalina upwards. There maybe a way to do it but not officially. You could maybe use VM Ware Fusion to run Mojave in Catalina but not sure if that would be a particularly seamless experience.

No - the Mac Pro (about to ship) and MacBook Pro 16 have T2 chips that lack any firmware support to run anything but Catalina. Since Catalina has been available for testing since June 2019, it’s going to be hard for a software company for professionals to say they can’t support it 6 months after the beta period started. You can run older OS in a virtual ...

The 16" MacBook Pro cannot run anything earlier than Catalina. Sometimes you can “downgrade” the operating system on a new Mac to an earlier version of macOS, but you should never count on it. If that Mac is completely new hardware (like the new 16" MacBook Pro) then Apple never adds driver support for older versions of macOS. If you order a Mac ...

it has all been explained so well in the earlier posts, but my guts feeling tells me that for the quick reader the inherent criticality may not have fully come across. So please forgive if i repeat most of the above statements, i just would like to try to put them into am more hands-on perspective. Lack of information You can't really estimate the ...

Unfortunately you have damaged the LCD screen which wont allow you to see any visual output until replaced with a new/working screen. I'm not sure about your location but iPhone repair shops/stalls are common place all over UK (hopefully USA too). If you feel confident simply a replacement via ebay or amazon following a step by step video guide like ' ...

The original Apple 1 came with a 256 byte ROM containing Steve Wozniak's monitor program. This program allowed the user to inspect memory, write to memory and run programs. There was also a very basic line editor that permitted the use of backspace and escape keys. The Woz Monitor Apple 1 emulator in Javascript If you want to try out the emulator, be ...

In short, yes, but there is a caveat. The SSD sticks are transferrable between those two models, no problem. What you have to be aware of is that as part of any major, and sometimes minor, macOS update, the firmware is also updated. This update, which can be important to have a specific OS version work well on any Mac, obviously does not get applied to the ...

The actual "bottleneck" here is the fact that your "theory" is incorrect. The Intel CPUs used do not support LPDDR4 memory at all. It won't work no matter what you do. They support only DDR4 and LPDDR3 RAM. Only the 10th gen Intel mobile processors support LPDDR4 - and the new MacBook Pro has a 9th gen CPU. The 10th gen Intel mobile processors have been ...

Unfortunately, unless a SMC reset doesn't work (Shut down -> Press Shift-Control-Option and Power Button at the same time for 10sec -> release keys -> Press power button), it is a hardware problem. If it's under warranty, Apple should fix it, if not, a 3rd party repair shop should be able to fix it for a reasonable price.

I have the same issue, Macbook Pro 2018 model 12'', I have no external keyboard connected, it just randomly stops working and each time the key is different. first it was a "t", then it was "i", then it was "m" etc. very weird, reboot always solve the problem but I seldom reboot unless I have too and I install no keyboard modifying software to interfere......
