MacBook Air 2 isnt mounting usb drives
Hi. I've installed new OSX Lion onto my dad's MacBook Air 2nd gen. The new OS has a couple of bugs. 1st is the WiFi dropping, but i see it isn't only my problem, so i will hope Apple will fix this in 10.7.1 ASAP. But, we found out that MacBook isn't mounting any USB drives. When I plug flash drive into mac, it doesn't show it. I have to go into Disk Utility and manually mount it. I have to do this with every USB drive. Flash disk, memory card reader, hard drive, everything.
Anybody knows how to fix this?
Thanks.
(sorry for my bad english)
It was probably a SMC reset here:
Shift-Control-Option keys and the power button

Or a PRAM reset
Command-Option-P-R keys

In my Apple Macbook Air, most of the USB Flash/Thumb Drives are not shown in the Finder Window. Only a few Brands of USB /Flash Thumb Drives are shown or compatible or shown in the Finder. How do I use any Flash/Thumb Drive with my Apple MacAir?
Yes, junker thumb drives pour like rain in the market.
Which makes are working on your Air, and which arent?
Stick to Sandisk and a couple of other reliable mfg. of memory sticks -
Back up iMac and macbook air to external WD hard drive
I have been using WD Mybook 2TB external hard drive to back up my iMac 27" late 2009 . OSX 10.9.3
(i think I use Time machine and not Smartware). Connected by USB2
1. When i recently updated my OSX I got the message that Smartware is not compatable and has been moved to non compatable folder.
2. I would like to back up my MacBook air to the same WD drive and I am not sure how to do this
I have checked several sites re formatting back up disk
and tried removing USB from Imac and plugging in USB from Mac book. The WD drive is recognised but only has one volume .
Do I have to add another partition to the WD Drive and will that reformat the disk and cause me to lose existing IMac Backup ?
I am an older person and not very tech savvy and I would appreciate any helpIf at all possible repartition the drive in order to remove their software. Backup using Time Machine or a third-party backup utility such as Carbon Copy Cloner 3.5.5.
I would not recommend partitioning your drive for each computer. it is not needed. Each computer will backup to the drive using separately named folders. All you need do is connect the backup drive to each computer. Now, I don't find this the most reliable or easiest method. That would be using separate backup drive for each computer. This way should one drive fail you only lose one back rather than both backups.
As for reformatting the drive:
Drive Partition and Format
Open Disk Utility in your Utilities folder.
After DU loads select the external backup drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
Whatever you do, do not try to simply delete the backup folder by dumping it in the Trash. This will take hours or even days. The above outlined process only takes a few minutes. -
I had iPhoto as part of iLife 11. I recently did an erase and install on my Macbook Air and without a CD drive I'm unable to reinstall. How can I install without having to repurchase all of the apps?
Do you have access to another Mac with a disk drive? If so you can do it in one of two ways:
1 - on the Mac with the optical drive launch Disk Utility and make a disk image of the iLife 11 disk. Connect the two Macs together and transfer the disk image to your MacBook Air. Mount the disk image and install from it. I have my iLife disks saved that way for quick and easy reinstall when necessary.
2 - connect the two Mac together so you can access the MBA from the Mac with the disk drive. Insert the iLife disk, and install from the second Mac to the MBA. -
Installation on a Macbook Air, with sounds on separate drive
Is there a way to install Logic Studio on a Macbook Air so that all the sound libraries and the recordings (and as much of anything else as possible) are on an external HD drive? Space is tight.
No, you got it. One USB port for Audio interface and the other for the streaming support files. I keep thinking of the 1st gen Macbook Airs with the one USB, sorry. The install is a very lengthy process made longer with the I/O limitations of the Air and USB 2.0 for the external support files. After you start the installer it will make sense with drop down menus for where and what get's copied.

Loading Adobe Photoshop on my MacBook Air (2014) without an optical drive
My lab at the University already has Adobe Photoshop. I am wondering how do I download it on my new MacBook Air (2014) without an optical drive.
Another query is about the usability of photoshop on MacBook Air. Mine is a 1.4Ghz, 128gb, 8mb (RAM) MAB. I am not a heavy user of Photoshop, but I need it once in a while for improving images from experiments. These images are mostly kept in a dropbox. I am wondering if the above specification sufficient.
Any help would be appreciated. ThankDownloads for most Adobe applications are available thru the following page:

What is the best way to partitioning Macbook Air 13" 2012 solid state drive
What is the best way to partitioning Macbook Air 13" 2012 solid state drive.
Tech,
You don't provide enough information onto which anyone could reasonably formulate an answer.
As mentioned, you don't indicate the circumstances that would warrant consideration of multiple partitions. Moreover, you also don't indoicate the size of the SSD in question.
Like Fred said, ordinarily you leave it alone as one. Some people like to keep data and the OS/apps separate, but it is for specific reasons. -
Pcmanfm is "Not Authorized" to mount usb drives
Hi,
I recently installed arch linux it's a nice distro but I got a few problem with it.
The biggest one is that I am actually not able to mount usb drives with pcmanfm this means that I am not able to use my old debian /home so far.
I tired multiple thinks (some of them are still active) e.g for example I used to setup a udev rules which wasn't helpful at all (and even after deleting this rule I always see server empty folder in /media (but that's another problem)).
Any ideas why I am not able to mount encrypted and not encrypted USB drives in arch linux?

Best Way to Create Multiple Partitions on Macbook Air 13" 2012 solid state drive (256GB)
I just bought a Macbook Air 13" 2012 solid state drive (256GB) w/ 8GB Ram and I would like to be able to dual boot to Windows 7 and have a 3rd partition to share files between both Operating Systems. Can someone point me in the right direction, recommend partition sizes, pros and cons etc.? Should i bother with the 3rd partition or just by an external HD?
FYI,I will mainly be using the MBA for programming in Visual Studio 2010 and some ios development. Thanks in advance.This, for example:
OS X: "Some features of Mac OS X are not supported for the disk (volume name)" appears during installation -

I cannot boot my 2012 Macbook Air 13" from external USB 2.0/3.0 drive.
I just purchased a new 2012 MacBook Air 13" with 8GB ram and 256Gb SSD. I have clones of my 2011 MBA drive made with Superduper on both a USB 2.0 and USB 3.0 external drives. The USB 2.0 drive enclosure contains the OWC Aura 256GB 6G SSD that used to be the internal drive for my 2011 MBA.
I cannot boot my new 2012 MBA from either external drive. When I try to do so, the MBA displays shows a gray circle with a line through it.
I can boot my MacBook Pro 2010 and 2007 Mac Pro just fine with either USB external drive. So, it must be something up with compatibility with the new 2012 MBA. All of my Macs are running 10.7.4 with all of the latest upgrades available as of 6/24/12.
Any suggestions?
Thanks in advance.
Bud JamesI have a drive I had been using in a 2007 MacBook that I would like to "upgrade" to a compatible version of 10.7.4 (build 11E2705), but I am having trouble finding a way to get the version of the OS on the drive without affecting the data on the drive.
I had hoped that booting from the Recovery partion on the SSD would allow me to "Reinstall 10.7" to get a compatible version, but the drive still can not boot the 2012 MacBook Air.
I may try cloning next, moving directories I want to keep to the root level of the target drive, but I wish there was an easier way to "refresh" the install of the OS to a newer version for new hardware.
I also need to find a way to "refresh" the USB drive I have for installing 10.7, to make sure it has the ability to boot new hardware, since the original 10.7.4 USB install clone does not boot the newest laptops. -
Why can't my macbook pro / macbook air read FAT32 external hard-drive?
I have a USB external hard drive that's formatted as FAT32. It worked fine under Windows and Ubuntu Linux.
here is what it shows under ubuntu:
Disk /dev/sdc: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x3a39bfa1
Device Boot Start End Blocks Id System
/dev/sdc1 2048 976773119 488385536 b W95 FAT32
As you can see its file system is FAT32, and as I understand FAT32 read/write is supported on all MACs.
However when I plug it to either a Macbook pro or a Macbook air, it said:
The disk you inserted was not readable by this computer.

New macbook air recognizes my external hard drive, but cannot read it
I recently bought a new Macbook Air about 3 weeks ago and I'm trying to access files that I have on my external hard drive. The macbook recognizes that there is an external drive, but when I click on it, the finder window is empty and it shows that there are no files on the drive. When I plug it back into my old Macbook pro (purchased in 2007, running Lion 10.7.5 ) I can access all of my files just fine. Also, a little while ago, while the drive was connected to the new laptop it ejected itself and gave me the prompt saying that the disk had been ejected incorectly. I'm wondering if there is something wrong with the disk because I did have to run disk repair on it once since it bricked. Or is it not compatible with this new macbook? I don't really want to shell out more money to buy a new disk, are there any programs I can install or new USB cables I can try? the disk is a Seagate 500GB portable expansion drive.
Hi Beth!
1) You need to plug the phone in with your USB cable. If for some reason it doesn't sync automatically, try clicking on the name of your phone in your lefthand menu of iTunes, and it'll bring you to a homepage of sorts for your phone.
2) From there, you should be able to click on "sync" at the bottom right of the page. Or you may have to go to the individual parts of your phone (where it says "music," "apps," etc. at the top of the page), and enable those to sync on each individual page.
3) That should do it, but you can always go back to that homepage from step 1 and click "sync" or "apply" once more to be sure everything syncs over.
If you've done this already, can you explain where you're seeing a red circle on your iPhone? Usually those red circles let you delete something if you click on them. For instance, if you want to delete an app, you hold your finger down on it for a moment and then the red circle appears so you can click again to delete.
Hope this helps you! -
Help! Macbook Air lost association with USB Airport hosted Time Machine Backup
Okay, so my wife's Macbook Air was doing Time Machine backup to USB drive attached to previous generation Airport Extreme...
We bought a brand new Airport router a couple of weeks ago, I plugged it in and everything went smoothly. Plugged in USN drive that attached to older APE router, and it's still visible on the network. However, ever since we got the new router, the existing backups are not associated with the Macbook Air anymore.
Yes, I can start over with a new backup file, but I was hoping to use the existing backup (it takes a while to backup wirelessly, and we lose the whole history if we wanted to recover previous versions of files that were backed up—I can't think of anything we'd need right now, but Murphy's Law will probably apply if I go ahead and erase the old and start new).
I was hoping all I would have to do was drag the old backup file onto the Time Machine icon to re-associate it with this computer, but I can't see any way to tell Time Machine, "hey, here's the backup file you are looking for... it's right here on the same USB drive attached to the new router."
(Also, before anyone says to make sure I have a backup of the backup, I do. The computer is backed up offsite with Backblaze, too.)
Perhaps it will be best to just start from scratch with a new Time Machine backup, that just seems like overkill, since there was nothing wrong or corrupt with the existing Time Machine file, I just switched what router it was attached to. Thanks for any advice/enlightenment.I guess I have a few comments.
Apple has an opt out.. they do not support Time Machine backups on older Airport Extreme. Apple have always stated it is unreliable and so refused to support it.. only with Gen6 of the AE have they changed to supporting TM backups.
From your point of view it should have worked.. it may indeed still work. But the change of network is significant and it will take some work on your part.
1. I need to know what OS is the MBA running??
2. Moving a disk from one network location to another, I would strongly recommend a full reset of Time Machine on the computer.
See A4 here. http://pondini.org/TM/Troubleshooting.html
3. Pondini in the same reference has some info about inheriting old backups .. slightly different context but it also could help.
see B5 and B6
4. It is also possible to move old backups into a new backup.. but this is then going too far.
I would simply buy a new USB drive.. and keep the old backup drive for a few months until your new one builds up sufficient history to be sure you will not need the old ones.. at that point you can use the old backup drive again after a reformat.
5. To do the new backup, since wireless is indeed a long and burdensome chore to make that crucial first backup, buy a thunderbolt to ethernet adapter.. assuming your MBA is recent enough. Ethernet is so worthwhile having it is required not optional extra. The cost at $35 is one of the cheapest adapters for a very expensive interface.. -
Automatically Mount USB Drive on TC
I have a USB drive attached to my TC and I use it for my itunes library. This works fine but when I use itunes on my macbook pro at home I must manually mount the drive. I would like to have the drive automatically mount whenever I am using my home network.
Is there any way to do this?johnvic, welcome to the discussions!
Open System Preferences, click on Accounts and then click on the Login Items tab.
Click the + (plus) button at the bottom of the Login box and navigate to select your Time Capsule disk. Click Add.
Time Capsule will open automatically the next time you restart your computer.
