How to use a Macbook Pro or a Macbook Air in Hindi - For Beginners Apple Menu - The apple menu is Mac OS is equivalent to the start button on a windows PC. We look at the following points in detail in this videoġ.
If you have recently purchased a mac or are shifting from a windows pc to a mac or are a beginner then this video is for you. This is an introductory video in the How to use a Macbook Pro or a Macbook Air in Hindi series. FWIW the answers above, whilst no doubt well-intentioned, are absolutely incorrect (as you'll quickly discover reading the MacRumours thread above - or even Googling basic SSD facts using search terms like "SSD ATA Secure Erase" etc).How to use a Macbook Pro or a Macbook Air in Hindi - For Beginners In this video we look at some of the basic menu options of Mac OS. With OS X there is no guarantee but this thread is probably the best list of options you can try if simply closing your lid for a couple minutes then opening it doesn't put your drive to sleep or if the Parted Magic option to 'sleep' your drive doesn't allow you to boot back into the saved state.
Your best bet is to download Parted Magic and click Start > System > Erase and it will open a GUI menu showing your available drives, select your SSD hard drive, confirm the next screen, and then it will offer you the option to put the drive 'to sleep' - which is easy to do on any system but OS X. Now if your SSD is locked (and I imagine it will be), you have to get it unlocked somehow which is so much more complicated than it should be. You can add -verbose to all of those to get more information, but I'd be lying if I claimed to have a clue about the output ) # hdparm -user-master u -security-erase-enhanced Eide /dev/sda Though for the life of me I cannot understand the difference between "Secure Erase" and "Enhanced Secure Erase" (especially as they are both completed in mere seconds (with Enhanced actually slightly faster, but I'm sure that's not the reason it's 'more' Secure than Secure (go figure), what I do is - quite simply - to do both: # hdparm -user-master u -security-set-pass Eide /dev/sda
(this is to 'lock' your drive for the ATA Secure Erase command, the "Eide" password can be another password of your choosing) # hdparm -user-master u -security-erase Eide /dev/sda If it's not locked, it's easy: # hdparm -user-master u -security-set-pass Eide /dev/sda This is to determine if your SSD is "locked" and it likely would be at which point things will either be difficult or very easy. To properly 'erase' all data from an SSD, you need to boot into a Linux distribution from an external drive (USB or SD or CD), open a Terminal and get to root however you prefer - I use: $ sudo su -īut if you boot using (which I think is your best option), you will be automatically logged in as root when you open a Terminal. Actually, they're technically worse than incorrect but it's not that important. Not going to help with that though.Īpologies if my answer is not applicable to your MBA as I have an late '11 MBA.īut for my MBA, the above answers would be incorrect.
If you don't have the USB drive you will have to obtain one somehow - which may mean taking the Mac to an Apple Store.įailing that, maybe you'll be able to acquire a install disk image from some place on the web and install it to an external drive that you can boot from. If you want extra security, you can use the Disk Utility while in the installation mode, by choosing it from the Utilities menu that is at the top of the screen.įrom there you can erase the disk, choosing from a range of security options when doing so. Run the installer and follow the instructions to reinstall the OS, at which point you should be given the option to wipe the current install and start fresh. It won't be easy to do what you want to without booting from something other than the System disk in your Mac.Īssuming you have the USB drive that shipped with the Macbook Air (you should have unless there is a good reason why you don't have it), you should insert it and boot from it, by holding the option (alt) key just after you hear the chime when turning the machine on.Īfter holding the option key for a short while, you will be presented with a choice of boot volumes, one of which should be the OS X installer. The Macbook Air should have shipped with a small USB drive that contains the installation software.
