Losing disk space after installing Mavericks
After installing OS X Mavericks, I had noticed my computer was losing disk space after updating some products. I even shut down my computer to allow it to readjust to the updates, cleared some unnecessary apps, and yet I see my computer losing more space, as if files are being added behind the scenes. I've adjusted my browser Safari to more private settings,even cleared the cache, to avoid this, yet it still occurs. Are there other files I should be clearing?
the trouble is I don't know what is causing the disk space to be taken. I'm idly using Safari with private browsing set, when I come looking at my finder, seeing the space gradually falling. I was at 695.02 GB available this morning, and now at 694.83 GB available. I've made no downloads in between then, so I'm wondering if this is the result of downloading Mavericks directly from the app store, or if there is a setting I need to fix. I've tried verrifying/repairing the disk, permissions too, but I still see the decrease occurring.

How many free disk space after install OS X lion (10.7) ?
Hi,
I would like to know that how many free disk space after install OS X lion (10.7) on MBA i5.
Many Thanks,
EricI want to buy MBA i5, I would like to free disk space of MBA 13" i5, Could anyone tell it to me? Thanks
As you're buing a new MacBook Air, it will come pre-installed with Lion. The actual installation will be somewhat larger than a "clean" Lion install as it will come with iLife preinstalled. Obviously, with an Air's limited storage space, you want to be sure that you have enough room for any applications and data that you'll want to keep on the SSD as well. It is fairly easy to upgrade the SSD on an Air:

The amount of RAM you have installed is probably more important. Fortunately, the newest 13" MacBook Airs all come with 4GB standard now. -
Losing disk space after upgrade of Mavericks
The download and installation was successful. However, after restarting and before upgrading all free iWork apps including iTunes and iPhoto. I noticed that after recovering about 10gb of disk space, it started reducing it again. I continued with the upgrade of the said apps, but after leaving my mbp for a few hours it started losing disk space again. this time its agresssive, i've lost around 40gb overnight, without using any apps or activating any updates. Please help!
It sounds like Time Machine is turned ON and the computer is making backups to the hard disk. This space is freed automatically, if required by the OS.

Slowly but continuously losing HD space after installing 10.9
I installed Mavericks a while back but didin't notice until recently that my available HD space is gradually decreasing with time. It got to the point where I only had ~200 Mb of storage left. Im on an older 2007 macbook running 10.9. I have a 45 Gb bootcamp partition, which is NOT losing space. Anyone run into this/know how to fix this?
This could be caused by caches and temporary files in your system. Have you been using your mac a lot? Have you been using very resource-heavy programs? These are all causes of cache/temp file size increase. Try deleting your safari history, safari cache, and any temporary files in the system. This won't completely stop the problem, as it'll keep using data, but you'll get it back when you do this.

Only 90MB disk space after installing iLife '11 - how to move iLife?
Hi, my installation of OS X is on a small SSD and I just barely had enough space to install iLife '11. I need more free disk space though so I need to move the largest iLife programs or maybe the whole thing. Obviously I wouldn't be posting here if the iLife '11 installer would let me install to my external drive but that wasn't the case. I tried "moving" iMovie but I got an error saying that I didn't have permissions. Thanks for any help!
MY LIBRARIES ARE EMPTY! So moving them won't help!Well - I partially figured out my own solution. You can move iLife. I moved the apple loops in /Library/Audio and all the iLife directories in /Library/Application Support to my storage drive. I made symbolic links for each folder I moved. Then I moved the apps to the other drive. I also moved my home folder - thanks Tom. Now I have 4GB of space back and I'm not seeing any more slowdown. I realize now if I have any other problems I'll just symbolic link more stuff off my startup SSD. Works like a charm for now. I'll update this thread if I run into any trouble. I ran GarageBand and all the loops play instantly off the symbolic links. So to all of you - remember to think creatively! My only alternative was to reinstall os x on the regular HDD - glad I took a moment to learn about symbolic links.

After installing Mavericks, I found that my Apple Apps (iBooks, App Store, Maps, iCalendar, iBooks, etc) will open but freeze or are none responsive. I have reinstalled Mavericks, did a recovery and reinstall, almost everything that I could find in other discussions. They only thing that helped was the recovery, until I tried to reinstall Mavericks. Someone please help.....
OS X Recovery does restore OS X meaning Mavericks.
Make sure there's enough storage space ...
Click your Apple menu top left in your screen. From the drop down menu click About This Mac > More Info > Storage
You'll see Available and Capacity. Make sure there's at least 15% available disk space.
The startup disk may need repairing ...
Launch Disk Utility located in HD > Applications > Utillities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If DU reports errors, restart your Mac while holding down the Command + R keys. From there you should be able to access the built in utilities in OS X Recovery to repair the startup disk.
Make sure to back up all important files first before using OS X Recovery.
OS X Recovery does require a broadband high speed internet connection. -
After installing Maverick my computer shut down and when it restarted I couldn't get to the home screen. The monitor was grey with some dark grey shapes, it sounded like it was constantly running a program. My computer is sick!! HELP
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 10
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -
Hello all, I could use some serious help on some major issues I have been having after installing Mavericks on my system (specs stated below). Never has a mac felt ever so rebelious and broken before in my lifelong period of using these systems. Anyway, after installing system 10.9, I had opened the mac App Store upon seeing that applications such as my iWork suite all had free updates. However, when I would attempt to navigate to the updates window, it would not respond to my various attempts. I then tried to get there by the system's menu bar and to my dismay, nothing would work when I clicked on it, not even the apple logo menu. I later quit the application using Command-Q and opened up the App Store by the apple menu option 'Software Update...' instead. Though it looked promising since the updates window did open, all update buttons or even '...more' info buttons were unresponsive. These same problems persisted even after restarting my computer. I had also attempted to see if repairing definitions would help by booting from the recovery start-disk and using disk utility but the repairs it carried out apparently had nothing to do with my issue. Finally, I was able to update to the new iWorks suite (which interestingly did not replace the iWorks '09 suite) by following the notification that asked about allowing automatic updates which I did.
Once trying to use Pages 5.0, I soon noticed that all I could do was merely type in a new document and change various options via key commands. Neither the inspector or top bar menus would respond to any place I click. Similarly, Evernote only starts up on the last used note and merely allows me to scroll through it. The top bar menus, the note select pane, and even clicking inside the note to input text are all not functioning and uninfluenced by any mouse clicks.
I have noticed other apps that will not respond to any sort of input, but I still have not explored all applications to know what the issues of each may be. However there are some applications that work such as Safari, Google Chrome, dolphin, iWork '09 including Pages '09, and others.
I do hope that I can avoid rolling back my system, but in the meantime, it has been quite the obticle course to use my computer for all of my school purposes.
Any help is very much appreciated,
Thank you!

How do I restore gid after installing Mavericks?
Hi folks,
quick question for you all.
Before installing Mavericks (I was running Mountain Lion), I was in the following situation:
I was user myname with uid=501, and
(besides other) I was member of a group called myname, which had gid=501.
Now, after installing Mavericks,
I'm still user myname with uid=501,
group myname still exists,
but now has gid=20, and
I am no more member of it.
As a result, a few files / folders which were accessible before installation, are denied to me now (listing them in Terminal correctly displays them as assigned to gid=501, which unfortunately seems to be unknown to the system).
How do I fix this (apart from changing file permissions)? I presume I should just
take group myname and change its gid back from 20 to 501,
add back my membership to it.
But how do I go through first step? And, more importantly, am I at risk of doing something wrong?
(And why on earth would Mavericks do that?)
Thanks in advance
SOK thanks I'll do that. I had actually upgraded to Lion, but when my data was read back to the new hard disk, obviously the upgrade wasn't. Thanks for your advice.

... With the latest software updates for OS X, I've read that anti-virus software is largely superfluous for Mac. Any opinions to the contrary/negative experiences?
Almost. Anti-virus software is completely superfluous for Mac.
I have tested most of the commonly available Mac "anti-virus" products under controlled conditions. The only differences between them are their varying degree of worthlessness. Some are malicious and will corrupt your Mac. The vast majority of Mac problems reported on this site are the direct result of using such products.
OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Disable Java in Safari > Preferences > Security.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind. -
My MacBook is mid 2010 or 2011 and was running 10.6.8. After installing mavericks my computer tries to boot, says it has to restart and that circle goes on and on. Disk utilities says everything is running okay and reinstalling mavericks twice didn't help. I was told my hard drive needs to be zeroed. How is that different from erasing and is it necessary as opposed to erasing? After I back up on an external drive (I know I should have done that before hehe) and erase or zero, what will happen to my operating system? Will I have the ability to reinstall mavericks or do I need to out a copy of it on the external hard drive? I'm wondering this because I don't know if my computer will be running snow leopard or anything at all after I erase or zero since I'm not entirely sure what those terms entail. Thanks for any help!
Ooops.
I upgraded my 10.6.8 system to 10.7.5. ..No problem, but my practice is to connect an ESATA dock to my macpro. install to the drive in the doc, use migration assistant to migrate my data and apps. use the os in the doc for 2 weeks, if no issue then I delete the OS partiton in my Internal System Drive, do a carbon copy clone to the internal drive.
I just did the similar to upgrade to mavericks. I installed to a new hardrive in my docking station. (black widow esata dock). I noticed 10.9.1 is slow stayed with 10.7.5 as my operating system. now and then I would boot 10.9.1 fire up the console utility and fix the issues that made it slow....
Now I am at the "burn in stage" mavericks is now running fast and stable. I'll use all my apps and if it does not break with the applications I run I will eventaully cc my 10.7.5 OS drive to the docking station, file the drive away.. and take my 10.9.1 drive in the doc and cc it to my internal system drive.
I always wipe out a partion when installing a new OS. Zeroing out is a bit more thorough, you will know if your drive is junk... but it's overkill for me.
I figured repartion is ok.
I'm 2 weeks away from doing a carbon copy clone from my 10.9.1 os drive in my dock to my internal drive.
by the way.. I am running Mavericks on a 8 core macpro 2,1. I have a modified bootloader that has an arbitration layer EFI32 to/from EFI64 emulated.
pretty cool.
And from new system standards, the old macpro stacks up pretty well: -

Click on the Desktop. Select Preferences from the Finder menu. Check the General and Sidebar toolbar items. See that the appropriate boxes are checked.

Creating a Mavericks USB boot drive after the horse has bolted. Can I create a bootable USB drive from my iMac after installing Mavericks without saving the Install OS X Mavericks.app file? Do I need to re- download the whole 5.29 Gb from the App Store again? My problem is my 4Gb/month allowance on a 12 month contract. I cannot purchase a data block from my ISP and although my speed is theoretically slowed to 64k after reaching my 4Gb, it actually ceases to download in reality.
HI tasclix, it depends what you mean by an OS X boot drive.
If you want a recovery disk from which you can reinstall (by re-downloading) or recover from a time machine backup, then nbar is correct.
If, however, you want to boot and run the OS X installer from the USB drive (so that you don't need to download again), then you will need a copy of "Install OS X Mavericks.app"; see this article:
http://support.apple.com/kb/HT5856
Before downloading again, search your system to see if the installer is still there - it's usually in the /Applications folder unless it has been deleted, but check your whole system for it anyway, you never know, you might still have it somewhere.
