The IPSW file type is primarily associated with 'iPhone/iPod' by Apple Inc.. This is a firmware update file for the iPhone. The file is a renamed .ZIP file. If you unZIP it you will see a file called MANIFEST.PLIST and a file without an extension but with a version number in the name, e.g., Firmware-14.5.3. This file is the firmware image. Source ...

You should know there is no such this as "BIOS" on a Mac (the equivalent system is called EFI, but you don't boot into it to change settings). To boot from a DVD or any other external medium, you'll have to hold down the Option ⌥ key while booting. Then you'll get a list with all the bootable devices and there you can select the device you want to boot from. ...

Currently there is no way to jailbreak either an Airport Extreme or a Time Capsule. Whilst they are probably in the same order of difficulty as jailbreaking as say an iOS device, no one has really spent any effort on doing so. Personally I think this is probably for the following reasons: limited target audience (low numbers of product in the world) ...

The line panic-info is the details of the last kernel panic registered and stored by the system. If you do a PRAM (or NVRAM) reset, those details will be removed. For example, I just ran nvram -p and I had no panic-info line because I did a PRAM reset since my last kernel panic. I can't even remember the last time I had a kernel panic. Hope that clears ...

The official answer to this is no, you can not restore to a previous version of iOS other than the current one available from Apple. This is because iTunes is attempting to obtain tokens from the Apple signing servers to authorize the device when restoring. The non official answer is yes, but requires some technical skills using iFaith. Post back if you ...

My understanding is only Cydia. Everything that changes the phone via jailbreak comes in via Cydia. :)

Firmware update and FileVault A forum post suggests that Firmware updates require access to /System/... in addition to the EFI partition (disk0s1). Since /System/... is located on the startup volume it is encrypted if you have FileVault 2 enabled - due to Full Disk Encryption. If you search further down in /System/... you will find the Revision number ...

The Mac equivalent of a UDID is a Serial Number. It can be found by click "About This Mac" in the  menu, and clicking twice on the version number.

system_profiler SPSerialATADataType | awk '/Revision/ { print $2 }' That should get you the current firmware version of your SSD. TPVABBF0 = has update TPSABBF0 = does not have update

I can confirm that this process works: https://fuerstnet.de/en/upgrade-crucial-m4-ssd-firmware-mac-without-cd There are many steps to follow, both in creating the usb disk, then in booting from it, but it took me to the firmware updater as promised. After all that effort, my disk was already up-to-date, but it did work. Crucial support says there is no ...

The guide provided by Crucial here is quite PC-hardware centric, that's why they talk about BIOS, I guess. Forget BIOS in a Mac context. You say you burned a DVD. I've downloaded the ISO file from the update page, burned a CD and I couldn't boot from it either when pressing 'C' upon restart (as explained here: http://support.apple.com/kb/HT1533]. The CD ...

EFI firmware updates are 'staged' in the normally hidden EFI partition on your disk, which typically resides at device /dev/disk0s1. Once in single-user mode, you can create a folder in which to mount this partition, then mount it like so: mkdir /Volumes/efi mount -t msdos /dev/disk0s1 /Volumes/efi From here, navigate into the /EFI/APPLE/FIRMWARE/ ...

Using the Intel power gadget (above) shows your CPU running at low speed. In normal case that would be fine if there is no load. I have MBA with 1.8 GHz Intel Core i5 and runs at 0.85 at normal use, how ever it does spikes to 1.8 + under load. Since the computer processing speed depends on more than one factor (CPU +SSD read/Write+RAM)... I would say you ...

I downloaded the Crucial_m4_040H-04-00.zip and followed this tutorial and everything seemed to work for me. I hope this helps.

If you have another Mac, boot the laptop in Target Disk Mode. Running the disk alone shouldn't heat it up too much. Zero-fill the disk. Then, install a fresh OS.


1

If the computer had sensitive information on it, you really should perform a secure erase, but in order to do that properly you need to start from something other than the disk you're about to erase. The easiest way to do this is to get an erasable USB flash drive (at least 1GB) as a recovery disk: Convert the flash drive to GPT partitioning: plug the ...

If overheating is the problem I would try doing the clean install while having a fan blow cool air directly onto the computer into the vent openings. I may even remove the bottom covers to increase airflow. If you are selling for parts, why not remove the hard drive and sell it drive-less, then take a hammer to the drive itself to protect your data.

In short: not if you didn't bother about jailbreaking or never heard of TinyUmbrella. Apple is very strict on installing iOS firmware. Everytime you do a restore, iTunes is verifying the firmware for the connected device with their own server by checking SHSH blobs at Apple's servers. An app like TinyUmbrella allows you backup your SHSH blobs (they are ...

Here's a helpful guide on using TinyUmbrella, SHSH blobs, and downgrading. Depending on your hardware, downgrading may or may not be possible. I haven't tried downgrading anything since iOS 5 beta on original iPad and iPhone 4. It worked in both cases, but I'm not sure what you have. The version of iTunes may also play a role in your ability to downgrade. ...

Heres a short overview. The term "firmware" for iOS devices covers some or all of the following items dependant on the device: the baseband (the phone code implementing the cell tower communications for voice and data) the device firmware (akin to the BIOS) otherwise known as the boot ROM the device software (iOS itself) Devices like the iPod touch and ...

I had the same issue and this is how I finally got the update to install. disable firmware password disable filevault reboot and shutdown reset PRAM reboot install the update (when the update was done, my mba was shut down, so I had to power it on again myself) (enable filevault and firmware password again) You can check if the update was successfully ...

After disabling FileVault 2 you might have to do a SMC reset to have a successful update ( and new revision ). See http://support.apple.com/kb/HT3964 to see how. If you've been successful can be seen in your systeminformation panel under Hardware -> Serial-ATA -> Version.

I had to perform the SMC reset twice after this exact thing happened just now. After the second reset, it booted and finished the firmware update.
