I am having trouble erasing the hard drive in my Macbook Air

I am having trouble erasing the hard drive in my Macbook Air. When I enter Utilities and attempt to erase the buttons are frozen both security and erase

You need to restart with the Option key held down, boot from the computer's original thumbdrive(if any) or the recovery partition(10.7+), and erase the drive from there.

Following having to erase the hard drive, I am attempting to re-install CS5 upgrade........

Following having to erase the hard drive, I am attempting to re-install CS5 from previously registered CDs as an upgrade to CS2. Although at the time of purchase, CS2 was acceptable, and the serial numbers of the NEW software remain registered on my 'account', the serial number of the original CS2 is now rejected as UN-acceptable, the oldest version now acceptable seeming to be CS3
What do I do????

can you select cs2 as an upgradeable option in the dropdown box after entering your cs5 serial number?
if yes, use this serial number, Error: Activation Server Unavailable | CS2, Acrobat 7, Audition 3
if not, contact adobe support by clicking here and, when available, click 'still need help', https://helpx.adobe.com/contact.html

I am having trouble with the "numbers" app on my MacBook Air. I go to print my document and that works just fine. I cannot however return to the document after printing. What do I have to do?

RR,
Not to worry, you're not the first to expect Print to finish by returning you to the edit mode. The thing is that Printing is so hit and miss with this version of the app, you will probably want to stay in the Print window for more than one attempt.

How do I mount the hard drive of one Macbook Air onto another Macbook Air?

I did something funny to my Macbook Air (late 2009). However I have a brand new Macbook Air that I just took out of the box today.
I want to check the hard drive of the old MBA and remove some files as I filled up the hard drive by mistake while I was backing it up.
Whenever I start the old Macbook Air, it shows a blue screen. I can see Yahoo Widgets but the dock is off the screen.
How do I mount the HD of the old MBA? I have two USB ethernet dongles. I have an ethernet cord.
Can I simply connect them up via the USB ports? Will that mount the old MBA onto the new MBA?
I am in serious trouble because I don't have a backup. I wrecked the hard drive while I was doing a backup. I am trying to salvage whatever I have on the hard drive of the old MBA.
I think I can salvage a lot. I just can't see the Desktop of the old MBA when I start that computer up.
As my new MBA has 256GB I am going to try and mount the old MBA onto the new MBA and remove some files from there.
Can it be done like this?

Thanks for the reply. I was able to save the data on the Macbook Air whose HD got corrupted by using File Sharing (ethernet connecting two Macbook Airs).
I am also going to make a disk image of the HD using Disk Utility and mount that Disk Image onto an external hard drive. That way I can save the hard drive contents.

How do I acces the hard drive on my Macbook air as a target with out firewire

My Macbook air boots to a blue screen. Can I connect to another Mac via USB or etherent to access the hard drive? I did a disk repair through the disk utility but that did not solve the start up issue.

Clone it using Carbon Copy Cloner. Here's the link:
http://www.bombich.com/
Then to move it to the MBair and boot the Air holding down the Option key between the startup tone and the Logo / pinwheel.
The boot manager will start and then select the external drive as the boot device.
First some qualifying questions:
1. What OSx release is on your other Mac.
2. What MBair do you have.
I want to make sure the OS you're going to clone is more recent then the OSx that your MBair originally shipped with.

How can I upgrade the hard drive in my MacBook Air early 2014 11"?

i have a macbook air with a 128gb ssd drive and want to install a larger drive. where can I buy the drive from and how do I install it?

At the present time there are no third party PCIe SSDs available. Until some are produced for sale, the only alternative is to purchase a MBA with larger storage.
Ciao.

I need to wipe the hard drive clean on MacBook Air, how do I do this?

I have a Macbook Air that I want to wipe clean. All the discussions I read talk about rebooting with disk, but Air does not have one?

Reboot the system, hold command-R to boot into Recovery Partition.
Then you can use the recovery system to re-format the partition that hold the main OSX, and re-install OSX using the internet link. That last part may take a bit of time.
See the two DiskUtility screens that will clear that partition. The multi-pass erase adds time, but makes recovery of your data extremely difficult. Note that until you hit the final "Yes, I want to erase it" button, all can be cancelled.

Anyone having trouble with the trackpad on their new Macbook Air?

I bought the new (2012) Macbook Air 2 days after they were released. I have been using a PC forever and was looking forward to this being the right time to switch over to the Mac. However, my trackpad doesnt work well at all and it is to the point where I want to return this thing. Once the mac notices I am moving my finger it tracks fine, but if I stop for 5 seconds and resume moving it, it will not pickup on the movement and I need to try many times before it starts tracking properly. This is most annoying and from my point of view makes this otherwise beautiful laptop unnacceptable. I have tried plugged and unplugged as I read this an issue in earlier mac airs, but it doesnt matter. It seems like there is a software interrupt that is not a high enough priority and the computer get's busy about something else and forgets about the trackpad.

Turned out the hardware was bad. Apple exchanged it for a new Mac Air and the new trackpad works great. Thank goodness it was a defect. If the trackpads all worked like that I would have been bummed.

Installing a clean OS X Mavericks without erasing the hard drive?

Is it possible to install a "clean" OS X Mavericks (i.e. a fresh OS, NOT just upgrading over the existing OS) without erasing the hard drive? I might be dating myself here, but I recall being able to do this with previous OS upgrades. I'm currently running Mountain Lion and think maybe something has gotten corrupted. I am specifically having trouble with Time Machine. I'm hoping a fresh OS will fix it, but I'd rather not erase my hard drive. Since Time Machine isn't working, backing up and restoring the hard drive would be tedious.

Use the Disk Utility to repartition the drive, or install Mavericks onto an external one. The Archive & Install option was removed in 10.6.

So lately I decided I was tired of Tiger, and decided I would upgrade to Leopard. Well I made the mistake of erasing the hard drive before I made sure it would work. Well now like the installer was before it failed. And now when I boot it just won't work

So lately I decided I was tired of Tiger, and decided I would upgrade to Leopard. Well I made the mistake of erasing the hard drive before I made sure it would work. Well now like the installer was before it failed. And now when I boot I get the normal finder/question mark flashing folder. I also found a power Mac g4 that needs a new operating system. It's running 9.2. It's going to my grandma as a gift. I really need help.

I think you'll need to find a Retail 10.5 Disc.
Leopard requirements/10.5.x...
    * Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor
minimum system requirements
    * 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)
    * DVD drive for installation
    * 9GB of available disk space (I say 30GB at least)
Classic/OS9 Apps no longer supported.
Trouble is Apple no longer sells it, check eBay & such for the Retail version, not the Gray Discs...

There are workarounds if the 867MHz CPU is the only hangup...

How do i erase the hard drive and reinstall?

How do i erase the hard drive and reinstall everything? My computer is running slow and i thought with having a 2.4ghz processor and 4gb of ram would make speed not a factor but obviously i was wrong in that my comp is running slow. Not as slow as my pentium processor desktop but its too slow for my tastes. Im waiting to get an external hd so i can save my songs and pictures to before i do erase everything.

Go to finder and in Spotlight, type in erase and install. The second choice is "Reinstall OS X. Print that out and follow the directions.
Good Luck.

How do I properly zero out or erase the hard drives in my early 2009 Mac Pro 4,1 tower?

How do I properly zero out or erase the hard drives in my early 2009 Mac Pro 4,1 tower?
I assume there are already instructions on Apple.com someplace but haven't seen them yet… I have to one terabyte drives one the operating system the other is blank I want to start fresh I want to zero out both drives but I didn't want to make any mistakes
I know I can use disk utility to 0 Out Dr., #2 that means I will have to take out the operating system hard drive out of my 2008 Mac Pro and put it into my 2009 Mac Pro to use the disk utility to zero out drive one the OS drive in my 2009 Mac Pro am my correct
I just need a little bit a help I want to go slow so I don't make any mistakes with the sleds or with the erasing process which journaled to choose encrypted or not etc. etc.
Furthermore is there instructions on the site on how to change the hard drive into a different sled because the sleds and my 2009 are different than my 2008 any advice
Thank you

I'm doing this because my friend told me that zeroing out the drive can nap bad sectors and also later for some kind of diagnostics usage of the drive or something like that he wasn't really clear
My friend was really specific he said choose the option that writes zero's once over the drive that is plenty good enough I was inclined to use the maximum seven write ...I just want to make sure the drive has no bad sectors and that's it's it's zeroed out for possible future diagnostics usage or something that he said was usable later
he also advised me to run a test on it but I don't have the software you mentioned or the software that he has… So I may have to take the drives over to his house unless you have some kind of free software that's easy to use that you could suggest that will not only zero out the drive but test the drive completely
I am completely new to Mac I'm no dummy but at the same time I'm not super technically capable I mean I can surprise myself I'm pretty good but I need a good teacher… How expensive is this lifeguard software?
Thank you

Can I recover data from a reformatted hard drive? I did not do a back up prior to talking to Apple Support and the guy having me delete the hard drive and start anew. My bad but is all lost??

Can I recover data from a reformatted hard drive? I did not complete a back up prior to talking to Apple Support and the guy having me delete the hard drive (10.5.8) and start anew (10.6.3). My bad but is all lost?? Years of very important information....

You will need to purchase reovery sofware such as such as FileSalvage
http://subrosasoft.com/software/filesalvage
You can download a demo copy that will tell you what it can recover
If you want to recover that you must pay for the software then
When you do the recovery, you will need another disk drive to receive the recovered files
Having install a new operating system on the disk after the retformat is going to gradually reduce the amount of data that this software will be able to recover for you
