macbook pro – Liquid keyboard damage on MB Air – password keys don't work even with USB keyboard

A friend decided to disinfect the keyboard of another friend's MacBook Air. Some of the keys in your password no longer work, specifically M and P.

The strange thing is that we tested a USB keyboard and those keys do not work with the external keyboard either: typing M and P does not enter anything.

We also tested Dvorak's design. The "broken" physical keys work, but the keys assigned to M and P do not work.

When I log in as a guest user, the USB keyboard works fully, but that doesn't help much.

It seems that some kind of software keyboard module was fried? I can't think of a good explanation.

We are currently unable to log into the computer at all.

Can anyone help us, or at least give some guidance on how we can back up the computer?

Windows 8.1 Pro software license

I have purchased a key from an e-commerce website. It is found to be Windows 8.1 RTM pro Retail. I have verified it through show key. Can I use it if it is legal?

macbook pro: is there any way to clear update data for Software Update (System Preferences)?

I am trying to upgrade from MacBook Air 2017 from Mojave 10.14.6 to Catalina 10.15.4 via Software update available in System Preferences app as below:

I tried to download this update earlier, but there was a network problem and around 500MB of the update was downloaded. When I tried to download this again it continues downloading from this point and then fails. If I restart it, it continues again from the 500MB point.

Is there a way to clear the update cache for System Update so that I can download the update again smoothly?

I tried following the instructions in my own question for Sierra, but that doesn't seem to help (probably because the location of the update cache has changed when system updates were moved from the app store to System Preferences).

macbook pro: ~ 10 tries are needed to start my mid 2012 (first with retina) MBP 15

It was October 2019 when I used the computer in the rain. For a few days I had some issues with the touchpad, then it fully recovered, and then the entire machine died. Since then I was able to use the laptop maybe 5 times.

At first it didn't start at all, then it started once with no touchpad or keyboard response, slow as hell. Then, after a few months, the situation recurs: when connected to power, the catalog icon blinks until the battery is depleted or disconnected in a difficult way. It hardly ever starts correctly, and if it does, it works perfectly fine every time. Is it a hard drive? I have an OWD disk, I don't know the history of the computer. A boy at a local third-party Apple store told me that the keyboard, touchpad, and maybe the hard drive need replacement, the hard drive may die anytime soon. Here is an error code:

MacBook Pro 2017 has no startup disk when upgrading MacOS beyond Sierra

My 15 "2017 MacBook Pro displays a flashing question mark every time I try to upgrade to a newer operating system. The installation process seems completely normal until it is last restarted and boots into a flashing folder. When I look in recovery I see my SSD and the MacOS base system, first aid on any of these does nothing. From the startup disk inside recovery I don't see any available disks. Starting while holding the option shows the SSD as EFI boot, and the boot It shows a slightly different installer that also fixes nothing.

I can restore Internet to Sierra if I want to, so I keep doing it and have tried updating to High Sierra, Mojave and Catalina, all of which have had the same problem. I've rebooted the RAM and SMC, I've done clean installs and reinstalls on every operating system with and without first aid on every visible drive beforehand, the only way I can boot the laptop is by doing an internet recovery back to Sierra, at which point it works perfectly. Completely erasing the hard drive and trying clean installs of each operating system has also not worked through internet installation or usb installation. I've tried some recommended terminal commands for this kind of problem, but I don't remember exactly what they were (several were about mounting and mounting drives). I am not comfortable or familiar with the terminal at all.

I don't care about data recovery or anything like that, I just want a newer operating system because Sierra no longer supports a game my friend plays a lot. At this point I am a little lost. I'm a Windows person fixing this for a friend, so the fact that a clean install didn't work is a little annoying. Any help or advice is appreciated, thanks.

macbook pro – How do I keep the microphone on while I dictate?

I have a Macbook pro with Catalina. When I dictate and then pause, the microphone turns off and I have to press the fn key twice to turn it back on. With Dragon speak, you can say Microphone on, but this doesn't work here. I have tried dictating with both Open Office and Pages, and the problem is the same. I want to use dictation to dictate stories, and this involves pauses.

How to disable / block Microsoft Store in Windows 10 Pro by firewall?

I want to lock Microsoft Store on Windows 10 pro in a corporate environment. After reading relevant articles on this matter and testing them on my machine, I see that Windows 10 Pro does not support this feature (either through Group Policy (not recommended by my Administrator) or the Registry.

Now, I choose another solution, that is, block it with a firewall. If feasible, can anyone show me the rules on how to block Microsoft Store by firewall? I am using a tool to configure this rule.

network – Macbook Pro (mojave) cannot connect to new router

my landlord set up a new router and provided me with a new password. However, I cannot connect to the Internet.

After typing the password, an error appears saying "The wifi network requires a WPA2 password" and "Invalid password"

Initially I thought you should have used the security key instead, but that also returns the same error.

I went to open network preference -> advanced, and created a new preferred network. However, this also returns the same error (& # 39; The wifi network requires a WPA2 password & # 39; and "Invalid password")

Can anyone point me to suggestions on how to fix this?
