I have already tried to reset SMC and NVRAM/PRAM.You can do this using Disk Utility, an app that comes with every Mac. There is no peripheral attached. The progress bar reaches the end and the computer won't boot anymore. Eventually it got stuck on boot screen. Today when working my MacBook Pro (2016 with Touch Bar) simply started to have multiple Kernel Panics on a loop. Mac won't boot, Disk Utility won't load.
Boot For Disk Utilities Free Feature AvailableConnect a USB drive to your Mac. Download, install, and launch Disk Drill. Indeed, this lack of physical media is perhaps the biggest complaint about Lion’s App Store-only distribution, as there are a good number of reasons you might want a bootable Lion installer, whether it be a DVD, a thumb drive, or an external hard drive.Disk Drill offers the ability to create a bootable drive with a simple process that is available as a free feature available in all versions of the software. Unlike previous versions of Mac OS X, Lion (OS X 10.7) doesn’t ship on a bootable disc—it’s available only as an installer app downloadable from the Mac App Store, and that installer doesn’t require a bootable installation disc. On Intel-based Macs, restart your Mac and hold down Command-R.![]() This drive must be at least 5GB in size (an 8GB flash drive works well), and it must be formatted with a GUID Partition Table. Connect to your Mac the hard drive or flash drive you want to use for your bootable Lion installer. Drag the Mac OS X Install ESD icon into the Source field on the right (if it isn’t already there). However, with the 10.7.4 installer, you must use the mounted Mac OS X Install ESD volume or you will get an error at the end of the restore procedure and the newly created bootable drive may not function properly.You can use Disk Utility’s Restore screen to create a bootable flash drive or hard drive.In Disk Utility, select InstallESD.dmg in the sidebarWhen prompted, insert a blank DVD (a single-layer disc should work, although you can use a dual-layer disc instead), choose your burn options, and click Burn.You can now boot any Lion-compatible Mac from this drive or DVD and install Lion. The restore procedure will take anywhere from five to 15 minutes, depending on your Mac and the speed of your drive.Note: In versions of the Lion installer prior to 10.7.4, you didn’t need to first mount the InstallESD.dmg image—you could simply drag the image itself into the Source field. Click Restore and, if prompted, enter an admin-level username and password. Warning: The next step will erase the destination drive or partition, so make sure it doesn’t contain any valuable data. In Disk Utility, find this destination drive in the sidebar and then drag it into the Destination field on the right if the destination drive has multiple partitions, just drag the partition you want to use as your bootable installer volume. Hard truck 2 king of the road windows 7 patchAs I explained in our main Lion-installation article, you should be able to force a re-download using one of the following three tricks: First, Option+click the Buy App button in the Mac App Store. If you don’t, you’ll have to re-download the entire thing from the Mac App Store.If you’ve already installed Lion—so it’s too late to move the installer—you’ve may find that the Mac App Store claims that Lion is already installed and prevents you from downloading it again. So if you plan to use that installer on other Macs, or to create a bootable disc or drive as explained here, be sure to copy the installer to another drive—or at least move it out of the Applications folder—before you install. ![]()
