Slow Mac after OS X Yosemite Update? Fear not !

When I installed OS X Yosemite, my first impressions were : “WOW”, “Amazing”. But two after the installation, my MacBook started to get slow. There was heavy Ram usage. Oh, I almost forgot. Just after the installation, web pages in Safari were loading so slow. Since so many people are having these issues with the new operating system released by Apple, I thought of sharing the methods that I used to get them resolved.

Solution for slow loading of web pages in Safari

  1. Go to Macintosh HD in Finder and open Library.
  2. Open “Launch Agents” and “Launch Daemons” (one at a time).
  3. See whether there is anything related to “Parallels”. If there are any “Parallels” files, move them to Trash.
  4. Empty the trash.

Voila ! Safari is now fast, eh?

Alright. The next was the most painful thing. Slow computer…OMG !! There was heavy RAM usage in the Activity Monitor. Three processes, namely “coreaudiod”, “identityservicesd” and “callservicesd” were not responding. I contacted Apple Support and they asked me to do a Disk Repair and Permissions Repair but the problem persisted. Then they asked me to do a clean install. Well, this was frustrating since I did not have a backup of my hard drive. I did not give up. Googled the issue and found out so many people are having the issue.

Luckily, I found out that in Audio Midi Setup under Utilities, there was a Digi CoreAudio device which I had no clue from where it got there. This problem can arise if you had Pro Tools installed in your Mac.

Solution for heavy RAM usage and non-responding services

  1. Find Digidesign CoreAudio.plugin in the following path : /Library/Audio/Plug-Ins/HAL
  2. Delete the plug-in and remove it from the trash.
  3. Reboot the system.

My laptop was fast after taking these steps. Goodbye “Not responding” processes ! This also solved the issue where the dock remains when I shut down my Mac, which terminates the shut down process and I had to force shut down.

N.B. There might be an audio device with a different name, in which case, you need to remove the plug-in associated with it. However, the path for finding it will be the same.

I hope this post helps for the people waiting to get these issues solved.

Producing Music

I have been using Apple loops found in Logic Pro X software for my tracks (except for the first one). After sharing eight tracks on Soundcloud and being satisfied with eight likes, two comments and 82 plays (which I never expected), I thought, “Enough with loops. Why not create my own melodies and beats?”

Then, I had to think of a suitable melody and a beat for my next track, which was not easy because it should be made unique and grooving, so I placed some notes on the piano roll of Logic Pro X software and did a playback. The starting and the middle sections were great but the end was not that good. After fiddling around with the notes, I finally managed to get a fine melody. For the beat, I listened to some sequences in the “Boom” plug-in found in Pro Tools to get an idea and drew the notes on the piano roll again.

My next step was to figure out how to get the “whoosh” sound found in electronic tracks, which can be created from white noise. After watching some tutorials, I was able to do this using the “ES P” and “Autofilter” plug-ins. A screenshot showing the two plug-ins can be found below:

Currently, I am investigating on filter sweeping and time compressing, so that I could get the “weew” sound found in electronic tracks (for example, in Vicetone’s remix of “We Come Running” by Youngblood Hawke).

Here are the tracks that I created after the three tracks found in my previous post. Hope you would enjoy them. One of them is R&B.
