I am working on customizing a SharePoint Farm and it's Master Pages. I have had substantial success altering the general Site collections within the 15\TEMPLATE\GLOBAL path of the Hive through the Seattle.master file. Even the 'Site Contents' and 'Site Settings' pages adhere to the alterations.
I will not be using any feature stapling techniques, and have no problems with editing the source files in the Hive. I am completely aware of the consequences.
My issue arises with the My Site site collection. I am unable to alter a Hive based Master Page to affect this site. The mysite15.master pages within the '15\TEMPLATE\Features' directory do not affect the sites. I am forced to alter the mysites15.master file that is relative to the My Site site collection through SharePoint Designer to get the desired effects, however, only the 'Newsfeed' and 'About Me' sections are altered. The 'Blog' section of the My Site site collection is altered with the Seattle.master page in the GLOBAL folder.
My question is, how do I alter the 'Apps' section (MySitePath/_layouts/15/viewlists.aspx) and the 'Tasks' sections (MySitePath/AllTasks.aspx) of the My Site collection?
