You should not be manually placing anything in the Receipts or Application Support folder or 99% of the time the Library folder and any subfolders itself. The system and apps will take care of what belongs there. Your documents should go into the Documents folder or any other new folder you create for storage in your home folder. Also don't place any of your documents in the Applications folders.
As to why the apps are appearing twice. If you have your Applications folder backed up to another drive/location, this can cause the apps to appear twice. Using Onyx under Maintenance-->Rebuild, run the LaunchServices option. This should reset to only seeing one set of apps. Note that I've found that if you open the backed up copy of the Applications folder again, it will likely cause the double app list again.
I am a novice in system issues, with a limited technical vocabulary, so please have mercy?? Sorry if this message is lengthy.
Am trying to understand why, lately, I have to use install DVD 1 for minor boot disk repairs on my Intel iMac (late 2006-17" - OSX 10.4.11) almost every week. And why, when I right~click on a file to open it, all applications are proposed twice. Makes the list sort of long!
Not knowing what to look for I first thought I might have missed a firmware update. My computer says I'm up to date with EFI 1.2. I make all updates proposed by system as soon as they appear, and regularly use Onyx for privileges repairs, particularly before and after DLs, use Automation weekly, etc. (But I still haven't found out what precise iMac the EFI 1.3 is intended for).
After scavenging heaps of forum threads and seen remarks saying that Library is to be used with great caution, I wonder if that's the problem. But can find absolutely no/nada detailed explanation concerning OSX Libraries in my litterature (the usual "missing manuals) nor on-line (Apple-site, forums, CNET).?
I did realize that the MacIntosh HD Library was something to avoid tampering with.
But so far, I thought the User ("little house") Library was my own set of private bookshelves. I.e.
- User>>Library>>Receipts file: contains all .dmg, .pkg and zip files for all software, Apple and not Apple, in successive versions, that are installed on computer. Plus a couple of .dmg's for Tiger that I haven't installed but kept in case they should become difficult to find.
This Receipts file now weighs 8.4 Go.
- In Library>>Application Support file I have: (a) created manually a file for each installed app when such a file was not created automatically by install; (b) stored in each app file respective documents concerning purchase, registration keys, tutorials, updates; all of it sorted in extra subfiles per version (e.g. v4-2, v4-3, v5-01 etc).
I have of course kept everything that was created initially by installation procedures in this Application Support file. I now globally weighs 8.47 Go.
- One more info: the HD Library>> Receipts file- which I have not touched at all ? contains a mass of .pkg files, Apple and not Apple software, and weighs 524 Mo.
Have I created a mess, or is this more or less OK?
Very grateful for all helpful info.
