Apple Mail App, you alright mate?

Four days ago, Apple Mail app in my MacBook Pro, started to group unrelated emails from different email accounts into conversations. These had totally different recipients and subjects. Terrible, right? Well, let me go through the steps I used to solve the issue as lot of people (who are using OS X Yosemite in their Macs) are experiencing this.

First, I tried to rebuild the mailbox by clicking on “Mailbox” menu and then selecting “Rebuild” in Apple Mail app. The problem got solved, but temporarily. Bummer ! My next step was to contact Apple Support and they asked me to perform a manual re-indexing of the mailbox by taking the steps mentioned below :

  1. Close Apple Mail app (if it is already open)
  2. Go to the following path : ~/Library/Mail/V2/MailData/
  3. Delete every file that begins with “Envelope Index”
  4. Restart the computer and empty the Trash.
  5. Start the Mail app.

The problem was not solved. I tried re-adding the email accounts by deleting the previous ones within the Mail App. That was not the solution either. Repairing disk permissions and performing a disk repair through Disk Utility were my next moves. After realising that was not helpful, I contacted Apple Support again. Their next step was to create a new user account and see whether the problem persists. Too much work, right? Then, they asked me to reinstall OS X and if that does not help, perform a clean install. I reinstalled Yosemite by downloading it from the Mac App Store. Those grouped emails were not separated. There was no way that I was going to do a clean install as I thought that there has to be another way. Then I took the following procedure (If your emails can be accessed using a web browser, there is no need to be afraid of doing this or backing up your emails) :

  1. Close Apple Mail app (if it is already open)
  2. Open System Preferences and double-click on Internet Accounts.
  3. Remove the accounts (including Mail, Contacts, reminders…..everything !) where the emails are getting grouped unnecessarily.
  4. Open the Mail app and add the email accounts, which were removed.

Voilà! No more grouped unrelated emails!! I restarted my laptop just too see whether the problem has been solved, and it was solved indeed. However, if the problem arises again, please follow the four steps mentioned above. Also note that there is a possibility that emails in the same account (Outlook in my case) with different subjects could get grouped as well and the solution would be the same. This could be a bug in the OS X Yosemite and let’s hope that the software team at Apple will fix it soon.

Follow the above procedure if you get duplicates in the sent items as well (particularly if you have an Outlook email address). This method could also be applied if emails do not get received in your Outlook inbox within the Mail app.

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.
