ZR17 Posted November 30, 2017 Share Posted November 30, 2017 Hi all, I'm trying to install MacOS High Sierra v10.13 on the new Dell XPS 9360 with KabyLake i7 CPU. I was able to boot from USB, erase and format the SSD and run the "Install MacOS High Sierra" application successfully. However, after the computer reboots and the installation resumes, the OSInstaller crashes with the following message: macOS Installer(551,0x70000fa87000) malloc: *** error for object 0x7f8208c390fb: pointer being freed was not allocated. Thinking that it might be just a temporary issue, I rebooted the computer and re-ran the second phase of the installation but the error persists. Coming back to the error, another thing I could notice was repeated errors saying: preallocation not supported on this filesystem for /Volumes/bless.nrb6/EFI/APPLE/UPDATERS/MULTIUPDATER/... This happens numerous time right before the malloc error described before. I can't seem to find a similar problem anywhere online. Any suggestions and help will be greatly appreciated . Thanks. PS: Attached are the zipped CLOVER folder & the full Installation Log (the malloc error starts at line 544) CLOVER.zip Installer Log 30-Nov-2017.txt 1 Link to comment https://www.insanelymac.com/forum/topic/330136-dell-xps-9360-kabylake-macos-installer5510x70000fa87000-malloc-error-for-object-0x7f8208c390fb-pointer-being-freed-was-not-allocated/ Share on other sites More sharing options...
