Perhaps this has been discussed before but I posted about a slow running computer yesterday and I thought more discussion might be helpful to me as well as others. 

 

The first response I received had a link to MacKeeper which I followed and installed on my computer.  Long story...short.  MK scanned and alerted me that I had a couple of critical issues so I ran the clean up only to be alerted that everything would be "cleaned"  if I purchased the software.  The software threw my default browser out of whack so that FaceBook and YouTube were no longer working properly.  Luckily another forum poster gave me a link to clean MacKeeper off my computer.  It's amazing how insideous this sofware was but I finally got things back to normal.  Here's the catch...my computer has stopped hanging/buffering on videos which was the main complaint I was orginally having.  Moral...MacKeeper can't be all bad?

 

This episode prompted more questions for me.

 

 

1.  I was always told that with a Mac I need not worry about viruses/malware.  Is this a falicy?  If it is then, is there a reliable, hopefully freeware solution to optimizing my compters performance?

 

2.  My computer is two years old and I've had no problems...because of that I have neglected setting up Time Machine.  Now I will certainly turn it on but in trying to do that the first dialog box that shows up is asking about not detecting my wireless connection?  I'm confused since my wireless internet connection is working just fine.  Also I don't see what that has to do with backing up my computer. 

 

Seems like I had more questions but that's a start....

 

Thanks

    Hi Rusty,

     

    First issue, NEVER use MacKeeper...this has been discussed ad nauseum on here and everyone who has ever used that software has had nothing but problems.  And to make matters even worse, if you try to uninstall via the author's procedure you will not uninstall but end up with several hidden files that will give you more and more problems.  There is a thread on the uninstall that you can pick up by a simple search.

     

    If you feel compelled to use anti-virus software on a Mac, which is really unnecessary, you can get ClamXAV which actually IS a free download and highly thought of.

     

    To back up via Time Machine, the easiest method is an external hard drive connected by Firewire (the way I do it) or USB.  Partition the drive into a backup space and further user space.  I bought the 2 TB Mercury Elite Pro from OWC, www.macsales.com and it works like a champ.

  • Ralph Landry1 Level 8 Level 8 (38,210 points)

    After a quick search, this discussion has a link to a process by Phil Stokes that several say actually does the job of getting rid of MacKeeper.

     

    To reiterate, you really don't need to worry about viruses with Mac OS X but you do need to be vigilent about not clicking on popups that say you have a problem, get their software...there is no way they could know if there was a virus on your computer in the first place.

     

    I don't understand the message you are getting about TM backup and internet...TM needs an external drive to backup to rather than the internal...part of the theory that if you loose the internal drive and the backup is located there, you have no backup since you lost the drive.  You really need to look into an exernal drive, prices are pretty reasonable for good quality drives.  Setup is very easy with Disk Utility.

     

    Hope this helps with your concerns.

    This article "Beware MacKeeper" contains a list of mostly free alternatives to MacKeeper functions without all the hassle.

  • a brody Level 9 Level 9 (64,350 points)

    Even the alternatives for MacKeeper for the most part are not needed.   The only "maintenance", or regularly scheduled events you should run on your Mac include:

     

    1. Backing up your Mac at least twice* http://www.macmaps.com/backup.html

     

    2. Cleaning the system logs.  Anacron, and Macjanitor are probably the best known tools to do this if you choose to always shut down your machine at night, or put it in Energy Saver, and don't want it to preoccupy your machine's time the moment it wakes up.

     

    3. Keeping your system from getting too full* http://www.macmaps.com/diskfull.html

     

    Everything else, as Anheiser Busch likes to say, is "just a light..." (and no, I don't work for them, I just find their commercial humorous!)

    Seriously, if cleaning system caches the way some people do it around here with those tools was that necessary, wouldn't Apple have included it in the cron jobs

    for the logs?

     

    Cache files are there to speed system operations.  Cleaning them only slows you down, and if deleting one as it is being created happens, they get corrupted.

    Don't try to defeat the system at its own purposes.

     

    If you do start exhibiting system symptoms that would need such tools, your backup will always be a recourse anyway.   If you aren't backing up, then you are playing Russian Roulette with your data anyway.

  • Rusty K Level 1 Level 1 (0 points)

    Just to clarify...I believe that I did follow a helpful link on the proper way to rid my computer of MK.  So, if I'm getting the gist of the comments so far I should not worry about viruses/spyware/malware.  Until I noticed some slowness and buffering and I hadn't worried about it.  I will follow the suggestions for alternatives and I will definitely get my Time Machine working.  I do have an external hard drive that I was using for backing up certain files but that would not save my sanity in a crash situtation.

     

    Question:

     

    TM wants to reformat this HD.  Does TM do that with each backup?  Or in other words erase before backing up again?

  • a brody Level 9 Level 9 (64,350 points)

    No.  Only if the hard drive becomes full, or was changed with another that had no Time Machine status to it only to be switched back to the Time Machine backup, or you changed the files on it.  Time Machine generally needs twice the space of the original drive to make a full backup that has archival backups to go with it.  Check this tip for Time Machine.

    Running the maintenance scripts is over-rated as you can go for weeks or months before your logs start causing issues. But if you feel you must and you shut your machine down at night, Anacron won't solve the problem but PseudoAnacron will.

    #A Brody suggested - if cleaning caches was necessary, wouldn't Apple have included it in the cron jobs?    I think if it were necessary it would have been released as an app by now.   That it hasn't been, says it all.

    Apple abandoned cron for launchd years ago, but your point is still valid.

  • Rusty K Level 1 Level 1 (0 points)

    Ok...I do shut down every night.  Should I not?  It's just my habit to "turn out the lights"  when I go to bed.

     

    I'm still trying to get the back up thing straight.  My external is a 500G...I should just back up and not worry about it getting full as it will overwright?

  • Allan Eckert Level 8 Level 8 (46,735 points)

    I never turn my Mac off at night. The only time I turn it off is when I will be away for at least a couple of days.

  • Ralph Landry1 Level 8 Level 8 (38,210 points)

    I never turn off unless I will be away for a couple days...keeping it up and even in sleep mode maintains a constant temperature which the internals much prefer.

  • Rusty K Level 1 Level 1 (0 points)

    Just finishing up my first back up.  I looked in TM prefs to find out how to schedule backups but I found no options.  I'm assuming I can control TM manually simply by turning it off between backups.  I don't need to back up on an hourly basis.

     

    I do a lot of music recording which uses CPU.  Can this back up be going on in the background without effecting other ongoing opperations?

  • Rusty K Level 1 Level 1 (0 points)

    I see...if I keep auto backup off then it will only back up when I click "backup now".   Cool...I'll just do that once a week or so before I go to bed.

     

    Thanks everyone for you input.  If I notice my puter being sluggish I have the links for "fixes" you provided.

     

    Thanks again
