    Also, I checked my purchases tab in the App Store, and I see the OS Mavericks is there. Is it possible to just reinstall it again at this moment without any complications, or would that mess up my laptop even more?

    Hey I am having trouble with yosemite too. to make matters more complicated my Time Machine feature seems to be not working the way it should be.

    I was wondering if you downloaded Mavericks from the "purchased" menu on the App Store  and whether or not that way of reinstalling mavericks worked.. I'd really like my old computer back until they fix these problems. let me know ok?

    Thanks

    In order to return to a previous OS, you would need to invoke the recovery option, erase your drive using that Disk Utility, and then reinstall OS X. That should reinstall the original OS (if Lion or later); if Snow leopard or earlier, you'd need your original install disks to boot from, erase, and reinstall. You cannot go backwards without erasing your drive.

    This is read because it indicates the file has been modified by adding some entries for some reason. If you are already aware of the reason then you can probably ignore it. At least one variant of the iWorm Trojan does make such changes, but since you have apparently restored everything back to before that happened, it's probably not related to that.  In any case you can see what it says by opening Terminal (found in /Applications/Utilities/) then copy and paste the following line into the window after the "$ " prompt:

     

    cat /etc/hosts | open -fe

     

    and hitting return. This will open a TextEdit window with the information.  A normal hosts file looks like this:

     

    ##

    # Host Database

    #

    # localhost is used to configure the loopback interface

    # when the system is booting.  Do not change this entry.

    ##

    127.0.0.1 localhost

    255.255.255.255 broadcasthost

    ::1            localhost

    fe80::1%lo0 localhost

    Kernel Extensions:

      /Library/StartupItems/ArcanaStartupSound/Resources

      [not loaded] arcana.PRAM (6.1) Support

     

    Startup Items:

      ArcanaStartupSound: Path: /Library/StartupItems/ArcanaStartupSound

      Startup items are obsolete and will not work in future versions of OS X

    These seem to be left over from some very old software called StartupSound.prefPane from Arcana. I don't believe it has worked since Snow Leopard. You don't seem to have the Preference Pane installed any more, so you should remove the rest of it from /Library/StartupItems/.

    User Launch Agents:

      [not loaded] info.lokiware.attachmenttamer.cleanup.plist Support

      [invalid?] info.lokiware.attachmenttamer.setupagent.plist Support

    The developer posted the following about ten days ago:

    Attachment Tamer does not support OS X 10.10 Yosemite, which was released today, yet. But work on Yosemite compatibility is under way and you can expect a pre-release soon!

    3rd Party Preference Panes:

      Perian

    Perian has not been supported since Snow Leopard and reportedly started causing issues for Mavericks users.

     

    There are a couple more that I don't recognize, so hopefully you know what they all are for, up-to-date and Yosemite compatible.

    What you are describing is known as Internet Recovery, which is accessed by rebooting with <Command>-<Option>-R keys or if rebooting is unable to locate any bootable drive.

     

    If you use the Recovery System stored on your startup drive to reinstall OS X, it installs the most recent version of OS X previously installed on this computer.

     

    Details are @ OS X: About OS X Recovery.

    You can, but as babowa said, you will have to erase your hard drive to do that. Then you should be able to migrate user files, 3rd party apps and settings from your Time Machine backup.  If I were you I would have a bootable clone of your current hard drive available before attempting this in case anything goes wrong. Then you can restore from that drive and be back where you are now. You cannot boot Time Machine.

    Heres what happened. you told me about those files. i took care of them and tried to do a time machine restoration. something went wrong and i was stuck on the start up screen for 2 days total with no movement - just a spinning circle. I finally ended up stopping the process on the 3rd try and reinstalled the OS. when the computeer started this time (4th) it apparently restored all my files and brought me back the to the Time Machine date I has asked for regarding my files and applications BUT it left me with Yosemite. So in other words I now have September 3rd computer without iWorm files but now with Yosemite. In other words I'm right back to where I was in the beginning sans Iworm file (javaw or whatever) . so now I'm still stuck with legitimate problems i had before.

     

    my bluetooth does not work  - audio delays every five mins

    video delay in every facet - vlc, games, youtube, any moving video

    safari has massive cache build up since yosemite

    constantly thrwoing out trash to avoid system slow down including mouse trails

    no mail notifications and the only way to check email is to open the program. if i keep it open it slows the system even more.

    my icons are graphically a mess, they do no even look like images, just jumbled pixels.

     

    I'd try another restoration but it caused such a hassle for 48 hours at the worst time , I dont rely on that process any more no matter how "easy" it should have been. Id like to go back to mavericks but again I have no idea what will happen if I try another restoration and I've already deleted and updated al the programs I need which took another 2 days of straight throwing out trash (one process) just to clear up this system. and I'm only working with 300 gb of programs.

     

    this is the lowest I've ever seen apple in their roll out of anything. they wanted to be microsoft, well now theyre microsoft.

    Yes, thank you, I'm aware of that (and that was what I was really referring to and should have been more precise); however, I read a kb article which stated that newer Macs automatically boot into internet recovery.

    I had a problem updating to Yosemite as the installer froze on the load up screen. To get rid of the Yosemite update I took my macbook into an apple store and they had to revert it back to the factory settings and install mavericks from there. There are probably other ways to do this, but I'm not amazing with computers so taking it in to see an apple technician is probably your safest bet. Just back everything up before you do this though as everything gets lost when you wipe the mac.

    True, but that only happens when...

    "Newer Macs include the ability to start up directly from an Internet-based version OS X Recovery. Your Mac automatically uses this feature when the Recovery System on the startup drive isn't available."

    I must have missed that. This discussion has become over-subscribed and off topic in many cases. Apple did make adjustments to BlueTooth during development. Part of the problem is that it operates in the same frequency band as WiFi, USB 3.0 and many other household items, so the signal strength and sensitivity are very important. In addition, BlueTooth is now used for the new Continuity document Handoff capability so software had to be added to support that.

     

    I converse with over a hundred users daily who's job it is to report problems with Yosemite and I can honestly say none of them are reporting nearly as many issues as you are seeing and most of the ones you have mentioned have not come up. I spent most of the day updating many applications and utilities, almost all of which had made adjustments for Yosemite. I've really only had one mysterious problem with the computer spontaneously rebooting, even when I'm not using it or I put it to sleep. I established a second user account and when it doesn't happen when I'm logged into it, so I know it's some piece of software that is causing it, but the logs won't tell me which. Hopefully it was one of the ones that came out with an update this week.

     

    Based on my experience with Mavericks, I found that re-installing from the Recovery HD solved at least one major slowdown issue for me and many others that I talked to. I know you had a bad experience with it, but my guess was that had something to do with your Time Machine backup and not the recovery software. It only takes a few minutes (depending on download speed) to do a re-install which will not touch your user files or third party apps, but gives you a completely fresh system.

     

    Your EtreCheck report looks pretty clean now. Just need to wait for the Attachment Tamer update.

    If you use the internet recovery mode then you will be back with Yosemite because you have already installed it, Apple use the last OS installation as the recovery. like a lot of users I am not happy with Yosemite and reverted back to Mavericks and the way I achieved this was to use time machine and restored to a earlier working Mavericks, but it does not stop there! Yosemite will still be your internet recovery mode so you need to then install Mavericks from a disk or usb or download it from the the App store once installed you will finally removed Yosemite from your system.

     

    N.B

    This does not have to be a back-up from your machine, any will do as you we complete a clean install once you follow the last steps that i have put forward.

    well thanks for your help good to hear things seem to be alright regarding the etrecheck report again  thank you for your time.

     

    unfortunately none of what you said applies to me at all. i still cant watch a movie without having to quit vlc every 15 mins to sync the sound back up.

    safari is adding massive amounts of cache which i have to continuously throw out otherwise the whole system becomes even slower.

    my icons dont even look like icons they look like jumbled squares of color , my mail notifications dont appear at all and i see mouse trails daily.

    I'm following 4 other threads and i read people complaining about bluetooth issues all day. there is obviously some problem.
