Facetime and iMessages – How to fix (fast): “An error occurred during activation. Try again”

There is a time in the life of a mac user when you open Facetime or iMessages and boom! You get the activation error: “An error occurred during activation. Try again” 🤬

You put the AppleID and password and nope…same error there. 🤬🤬

Now as a normal person, you go online and Google that shit. There are tones of websites and videos but the guy at saintlad put together in very structured way 13 fixes.

The thing is, I did ’em all one by one and following Murphy’s Laws the 13th worked! 🤗🤣🤩 (you can try them all, they might work for you).

So what worked for me was this (deleting and let the system recreate the Mac’s Push Notifications file):

  1. Open Finder
  2. Go to your hard drive > Library > Preferences
  3. Delete the file com.apple.apsd.plist
  4. Enter the admin password when prompted
  5. Restart your Mac and login to Facetime or iMessages

Have fun! 😉

How to reset the password for the local Administrator account (or enable it) using Linux

If you have a personal computer maybe this is nothing you encounter very often.

If you have a computer in a network, in a domain maybe, you will definitely need at some point the local Administrator password. This occurs with various issues like the computer going out of the domain or user accounts problems.

There are 2 common situations:

  1. You know the Administrator password but the account is disabled.
  2. You don’t know/forgot the Administrator password.

The method below will help on both problems.

The Linux command used is chntpw.

Note: HirenBootCD uses the same application.

chntpw is not installed by default on Linux distros so you have to install it from your Package Manager.

I have it on a bootable USB flash with Puppy Linux. Here is my presentation of Puppy Linux.

DISCLAIMER!!! Resetting the Administrator password with this method is considered brute force cracking and not permitted in networks. It might be illegal in your area. The method below is only for educational purposes and you should never do that. System Administrators will detect that. If you can’t access a computer, always ask help from the System Administrator.

How to use it (i assume we use Windows XP but the method is use for other version of Windows):

  1. Boot the machine with the Puppy Linux USB flash.
  2. Make sure the Windows partition where the Windows folder is mounted.
  3. Open a Terminal and navigate to the location of your SAM file (in Windows XP is here: C:\WINDOWS\system32\config). For other versions of Windows find the SAM file location first.
  4. Type this at the prompt, without quotes: “sudo chntpw -u Administrator SAM“.
  5. Here you will be given some options. The 1st one is to reset the Administrator with a blank password and the 4th is to enable the Administrator account.
  6. Depending of your situation, enter a number and press [Enter].
  7. When the app asks you to write the SAM file, choose [y] and press [Enter].
  8. Reboot and login. If you enabled the Account, login with the password you knew. If you reset the account, use a blank password.
  9. Always remember your local Administrator password and disable the account after you did your job.

Happy day!

Windows 10 not showing in GRUB boot menu of Linux Mint

A rule of thumb for dual booting Linux and Windows is to install Windows first.

But as anomalies in the Matrix exist, doing so may cause to have only Linux in GRUB boot menu (the linux boot menu that let you choose the operating system you want to boot into).

There are GUI programs to fix this but i will show you the Terminal way. I know the linux Terminal is scary but you’ll se you have nothing to worry about.

Look at the bright side, it’s an exercise for linux Terminal and editing a text file.

So, it’s simple as that:

  1. Open a Terminal.
  2. Type without quotes: “sudo nano /etc/grub.d/40_custom”
  3. Enter your password.
  4. Add this to the file:

menuentry ‘Windows 10′ {

set root='(hd0,msdos1)’

chainloader +1

}

5. Save and exit the text editor.

6. Also on the Terminal, type without quotes: “sudo update-grub2”.

7. Enter your password.

8. Restart and enjoy.

 

Windows: File associations per user

If file associations are messed up on a specific user and the File Associations in Folder Options are correct, do this:

  1. Press [Win+R]
  2. Type regedit and press [Enter] to open Regedit (the registry editor)
  3. Navigate to HKEY_CURRENT_USER\Software\Classes
  4. Find you file type and see the software opens it. Usually the path to the software is messed up. Correct it and restart the computer.

I had a problem with .xls files on a single user like double clicking the file and nothing happened. If I opened Excel and did an Open for the file, it worked, but no double clicking.

NOTE: System wide file associations are in HKEY_LOCAL_MACHINE\Software\Classes.

Windows 7: Create new domain profile with the same name as an existing one

Original thread here and original of the original thread here. ^-^

  1. Rename the user’s profile folder to Bob.old
  2. Logged in as an admin, go to Control Panel → User Accounts → Manage User Accounts. Domain accounts show there after an initial login.
  3. Delete the account for Bob
  4. Open regedit and make sure that the user is no longer in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList. Delete it if present, even if it is followed by “.bak”.

Then you can login as bob to recreate the local user profile, then copy your user data into it. “
