Will having another OS on partition slow down my computer?
I have an early 2013 iMac (base 8gig RAMs, 1 TB harddrive, 2.7 GHz) that came with Mountain Lion. I want to partition my harddrive to install Mavericks. Will this slow down my computer's performace in any way? Also, if I keep going back and forth between Mountain Lion and Mavericks, will it harm the computer? Thanks in advance.
It may slow down your system slightly, depending on how full it is. With a spinning hard drive, it's the fastest at the outside, which is where the Mountain Lion partition is. So the Mavericks partition will be slower, but it may only be 10% to 15% slower for disk-related activities (assuming the disk isn't all that full).
But you also need to decide how you're going to handle your data: If you have a home directory on each partition it's going to be a pain. However if you DON'T (and attempt to share it), then applications that update their database (i.e. Mail, Notes, etc.,) may have data loss or otherwise corrupt things. So that's a risk.
Any reason you want to partition the drive? For the vast majority of users, Mountain Lion to Mavericks is a smooth upgrade. My recommendation would be to have a FULL backup (Time Machine, AND make a clone with SuperDuper! or Carbon Copy Cloner to an external drive). Then just upgrade. On the off chance that things do go terribly, you can just clone your drive back.

Is it worthwhile to load windows 7 onto my MacBook Air? Will it slow down my computer?
Is it worthwhile to load windows 7 onto my MacBook Air? Will it slow down my computer? What might be the benefits of having windows and mavericks as two different operating systems side by side?
Check out this article first. It deals with BootCamp vs Parallels Desktop but there are two other products: VMWare Fusion and VirtualBox that offer the same basic features as Parallels. So your first decision is which you prefer. As I said, I chose virtualization: Parallels Desktop in particular.
You need a full retail version of Windows - If you live in the States try New Egg for the best price. This is what I bought. You'll need it whether you choose BootCamp or virtualization. Note that Win7 apparently isn't available via download from Microsoft any longer, only Win8 so you'll need access to an external optical drive or use remote dvd sharing with your Windows computer. I've not tried installing Windows using remote DVD sharing but I have installed other software that way so I'd expect it to work if you choose virtualization. If you choose BootCamp you'll need access to an external optical drive or create an ISO image of Windows on a large flash disk. -
If my SSD on my Air is almost full, will it slow down the computer?
If my SSD on my Air is almost full, will it slow down the computer? As in, if I have about 20GB left on my SSD, will the computer run slower?
Rule of thumb tends to be that you should set aside 10% of disk space for SSDs for the best speed. This comes from SSDs in Windows PCs, where the SSDs do perform more slowly when full rather than having some free space. This is just how SSDs work, which I won't get into the technicalities of. The SSD controllers themselves allocate set a reserve space (this could not be true in Apple's case, depending on what chips they use), but generally the more free space the better. So 64GB should set aside 6GB, 128GB should set aside 12GB, and 256GB should set aside 25-26GB.
SSDs technically will never be as fast as when you first got it. They slow down as soon as you start to write data to them, but the slowdown will be negligible. It's still faster than a HDD at the end of the day. -
I have an older IMAC - purchased in 2007. Works well. I have LION iOS 10.7.5 and want to upgrade to Mountain Lion 10.8. Will it slow down my computer? If so, how much?

Music will slow down my computer?
Hi,
I have a MacBook Pro. On my old laptop (a MacBook from 4 years ago), the music slowed down my computer so much, to the extent that I had to get an external hard drive so that it would run at all. With the new MacBook Pro, I am debating whether or not to put my 14 GB of music onto the computer itself or to keep it on the external hard drive. Do they have more memory/a better system to hold large amounts of music and still run fast? Thoughts?No it won't slow your computer, unless you are getting very low on hard drive space. In you case with a new computer it shouldn't be an issue.

At first my laptop was fine after the earphone end got stuck in. Soon it started getting slower, and suddenly it stopped switching on. The people in the service station said that it wAs because the hard disk drive was corrupted. I came back home, and immediately it stopped working again. This time they said it was because of water spill. They changed the entire key board and then it started working for a while. Later I updated to maverick and that slowed down my computer. Once, I switched on my laptop, logged in, and then the screen went white. When we took it to the service center they said they will need to replace the hard disk. I am not sure what I should do. Any suggestions?
Liquid damage from water spill is progressive, unfortunately.

Starting my computer this morning I immediately was informed by Norton Security that RadioWMPCoreGecko 5.dll is safe. I don´t know this data and I want to remove ist because it slows down my computer. Has that something to do with Firefox? The Information of Firefox-Troubleshooting shows the following detail:
Gecko/20100101 Firefox/8.0.1
Can you help me?
Thank you in anticipation.To whom it may concern here the answer I received today from Norton Support:
''I would like to inform you that the RadioWMPCoreGecko 5.dll files was downloaded as an update for the Firefox browser which runs in the background and Norton program does not have any control on the downloads till it is safe.
If the download is safe, Norton program will notify you and will block, if file finds to be suspicious.''
Now I know what it is, but nevertheless my PC is still rather slow. -
My coworker's external hard drive slowing down my computer
Hello,
I have a question. My coworker plugged in his external hard drive to my iMac with a USB, and he has to run its files everyday through network from his computer. The reason he does this is because his old iMac cannot read his newly formate external hard drive. I feel like my computer is slowing down. Is what he's doing slowing down my computer? Is there a way to not let the external drive using my CPU or memory? Is there a way to set it to low priority?
Thanks.Since your current editing workflow is based around Virtual Copies there are no actual files containing the edit data. Therefore, you'll need to use the 'Import from another catalog' option ( see File menu).

Do I have go keep the music on iTunes once I have it on my iPhone as its slowing down my computer
Do I have go keep the music on iTunes once I have it on my iPhone as its slowing down my computer
Realistically, yes.
If you delete the music from your iTunes, you will have to use Manually Manage for your phone in the future because a Sync will attempt to remove songs that you have removed from iTunes.
More importantly, if you ever need to Restore your phone, only media in your iTunes Library will be added to your phone. So if you delete the computer's Library, you will have lost all your music. There are several discussions in this forum from people who have done this and have now lost all their music.
There is no specific reason why the iTunes Library should slow down your computer. Are you sure it isn't something else that is causing the problem? -
Is my 23,000 song library slowing down my computer?
Hi guys,
I have 23,000 songs on an external hard drive, and I wondered if iTunes writing the library file every once in a while, or any other cause, could be considerably slowing down my computer, why, and what I can do about it.
Thanks!
AlecAlec:
As I understand it, unless you were playing all your songs at once, your 23000 songs take up disk space, but don't slow down your computer. When you are running iTunes, importing music, or burning to CD iTunes will take up CPU capacity. You can watch the activity monitor and see how much of CPU capacity it takes up. If you don't find your computer underperforming in any way, you are fine. If you do, the cause is very likely elsewhere.
Good luck.

I just upgrade to Maverick on my 2 year old MacBook Pro and it has slowed down the computer terribly. All I see every time I do anything is that crazy circle going round and round. I don't recommend you upgrading. How do I get rid of it. I believe it forces you to buy a new macbook!!!!
It does not. First things first have you tried restarting?
Try restting PRAM

Try booting up in Safe Mode

Also open "activity monitor" and look and see what is using a lot of processing power. -
Hi Everyone. I have an old Mac Book with software updated to 10.6.8. I have saved a ton of emails in my inbox 'On My Mac'. There are so many it is slowing down my computer. Where do I find the folder with all the emails so I can cut and paste them to an external hard drive? Pls.help. Tks.
Depending on which email client software you use
the files should be in 'your home folder' library, esp.
if you use Mail application.... ~/Library/Mail
Since you don't specify what mail application,
that would most be associated with the file.
I notice there are some items to the right of your post
where it says "more like this' so that may be worth a
look to see if similar issues were answered. Also, the
Help viewer in your system is a searchable database.
Seems that google also brings up fair information, too.
Do you have a complete bootable clone of your entire
Mac system on an externally enclosed hard disk drive?
Good luck & happy computing!
