How To’s

The new El Capitan sound volume indicator sounds very hollow and empty to me. I hate it. So I found  a way to change it.

• Step 1) Disable SIP
  • Reboot your computer and hold CMD + R
  • Top menu bar, click on Utilities> Terminal
  • Type csrutil disable and press enter
  • Reboot
• Step 2) Navigate to: /System/Library/LoginPlugins/BezelServices.loginPlugin/Contents/Resources
  • Rename original file to volume_original.aiff
  • Copy and paste attached file into that folder, typing in your password as needed
• Step 3) Reboot

Volume File: volume.aiff

I’m in the process of upgrading a white macbook (A1342 Late 2009) to have an SSD, and because El Capitano appears to have lots of bugs/problems, and aesthetics are pretty bad I’ve decided to install Mavericks. Below are the steps I used/followed. Feel free to ask any questions!

1) If you have the “OS X Mavericks Installer.app” file provided follow steps on this link

Problem:
Soon after upgrading to Lollipop 5.1 on my Motorola g xt1031. I noticed that my car’s bluetooth receiver began skipping.

UPDATE 5/24/2017: There is no fix, skipping still continues, although less frequent. Rebooting fixes it temporarily.

Solutions:

• Revert back to the old music player.
  • Steps:
    • 1) Enable Developer Mode (Settings–>About Phone–> Tap “Build Number” until give access)
    • 2) Press back and you should now see a “Developer Options” menu item near the bottom of the settings screen.
    • 3) Enable “Use AwesomePlayer”
    • 4) Enjoy Skip Free Audio!
• Other things I tried:
  • Clearing the cache and  data from the bluetooth process
  • Re-pairing my phone to my car’s stereo

Problem: Sluggish and Unresponsive Calculator

My Ti-84 Plus Silver Edition became sluggish and unresponsive about 10 years ago. I bought a new Ti-84 and recently took out the Silver Edition one and tried to fix it.

Solution: 

• Use a compressed can of air and blow right into the I/O port and the USB port.
  • Dust particles are most likely shorting the signal. I was super skeptical to try it, I was 99% sure It wasn’t going to work, but it worked!!! 10 years too late :/ but hopefully it helps others!

As soon as I upgraded my Linksys E2500 V1 firmware to the 2.0 version, I noticed the 5ghz network would not broadcast, It kept stating the Channel and Band as “N/A” on the Status page even though they were both set to “auto”. Rebooted the router and even reset to factory settings and still nothing. This is an older router so Cisco probably didn’t spend even 1 minute testing this new firmware before pushing it to thousands of users who bought their product :/ . And they had the nerve to REMOVE the previous firmware so you couldnt downgrade to the previous version… wtf! It took some time but finally found a stock 1.0.07 firmware binary on a ddwrt forum. Flashed it and the 5ghz network came back right away.

Symptom: 

• 5Ghz network not broadcasted
