You can't update macOS High Sierra? You are on 10.13.x, but the 10.13.x +1  won't install? It goes through the download and reboot, but when it is done you are still on  same 10.13 ? You can't install kext extensions anymore ? Tried downloading combo updates ? Tried installing direct downloads ? You get in the logs:  Could not create a Preboot Volume for APFS install Or you get:  Could not update Preboot Volume  well... not anymore.. You don't need to reinstall or anything. Check your /Volumes/ folder you probably will see countless preboot volumes there.. This has to be a weird mac os bug. I had 99 folders, probably can't create anymore and hence no more updates for Mac os or no more low level kernel drivers installations... What you need to do is to delete all the folders except the Preboot one. So you should end up with only 1 preboot directory in volumes directory.. Reboot, reinstall and everythi...

Recently got an Asus tinker board , flashed images but no matter it won't boot. Neither android image or debian one. Turns out the problem was with the power supply. This beast requires really a lot power. If you run into issues , try to connect a more powerful usb charger. Apple's iphone charges won't do it.

in a windows server sometimes you just need to enable some ports on your firewall to your dynamic dns address.(such as RDP , FTP , etc..) It is cumbersome when you do this manually every time your ip address changes.Why not update your server automatically every time when your ip changes based on your new dynamic dns update ? 1 ) just create a powershell script like this: $ip = [System.Net.Dns]::GetHostAddresses(" your ddnss address ").IpAddressToString Set-NetFirewallRule -DisplayName " myrule " -RemoteAddress $ip Put in your ddns name like: xxx.dydns.org , no-ip etc.. Create a firewall rule and define ports etc. before hand and name it either "myrule" and use the second line as it is ,or change the "myrule" to your rule's display name on advanced firewall app on windows server. 2) name it as firewall.ps1 3) and than create a task on task scheduler like this: command to execute: powershell -executionpolicy remotesigned -File...

Windows 7 can't find files with extension *.pdb , try yourself: Open a directory where you know that there are files with *.pdb extension type search *.pdb and windows 7 will not be able to find any files and display error message: No items match your search. That's crazy bug ! It works as expected for other file extensions though . such as *.mp3 , *.html or whatever..

well they are real actually but not so angry
