Just a tip for wide ugly boot screen (if you can't get max resolution)

1 post in this topic

Recommended Posts

Hi! I just want to share with you my "solution" for my boot screen.


I think many of us having the bootscreen like this:


with that two bold black area on both side


My display native resolution is 1920x1080 but I couldn't get that resolution for boot screen.

So I simply found out what resolution I have by checking it in my monitor/display osd menu while osx was on the boot screen (for me it is: 1600x1200).

When I found out what resolution I have on the boot screen, I did this:

  • I went to /Extra/Themes/Default/ folder, and opened the theme.plist file.
  • Changed boot_height and screen_height to 1200
  • Changed boot_width and screen_width to 1600
  • Saved the changes to the theme.plist file.
  • Then I made an 1600x1200 size image in photoshop (you can use gimp or something else), filled it with black, and put a nice apple logo to the middle, then saved1 it as boot.png.
  • Backed up /Extra/Themes/Default/boot.png file.
  • Replaced /Extra/Themes/Default/boot.png with my 1600x1200 size boot.png file.
  • Rebooted.

(Green is your horizontal, Blue is your vertical resolution on the boot screen.)

1: Try to make the png as small (filesize) as you can (for better loading speed). I used multiple online png crush/compress tools to achieve this (google for "online png crush" or "online png compress").


Now I have a nice iOS-like boot screen:


I'm using this since I'm using a hackintosh (1,5years).



- make sure you don't have "Legacy Logo=Yes" in boot.plist.

- with the big boot.png, you can't see the spinning wheel (like in iOS)

      i have a little old mobo with socket 1156 no Sata 3 - biostar tpower i55 and i Was wondering if i had some chance to install a new nvme memory like Intel 760p.
      Due lack of support by my mobo i found a Pci Express card lycom dt-120 to expand my connectivity.
      After some researches i understood that i need a ‘bios support for the boot from nvme disk’. I want some of these nvme memory to install high Sierra and get a killer desktop.
      I think that i haven’t obviously a native bios support cause my mobo is pretty old, so i can’t get an nvme disk and install properly high Sierra hoping that boot?
      Or should i catch anyway? I Guess that same problem is for w10? 
      Thanks, Gabriele.

      Hi guys.

      Sometimes I am a complete noob, so I deleted two kexts from S/L/E and now my Asus Q200E laptop with OS X El Capitan boot hangs on kernel panic. I still can enter go through Clover to reach Recovery Mode and use Terminal, so I've put the two kexts on a USB pendrive and after some struggle I've managed to succefully copy them using Terminal, but the boot is still stuck on kernel panic. As I remember, these are the commands I've typed:

      mount -rw

      cp -a /Volumes/usb-stick/name.kext /Volumes/my-osx-drive/System/Library/Extensions

      Is there anything else I should do? Is anything wrong? Should I type some command else? For instance, should I type something to fix permissions and rebuild cache?

      Thanks a lot!

      I've been running High Sierra (Currently 10.13.3) on VMWare Player 12.5.9.
      I'm running it on a Dell XPS 15 9560 with the 4k screen.
      Currently I'm able to run OSX in either Native 4k resolution, or scaled to 1080p.
      I wanted to know if it was possible to add a 1440p scaled mode? Right now if I force 1440p resolution using VMWare tools, I simply get a smaller window with the virtual machine. So, as I understand, I need to add a HiDPI version of the resolution.
      Can anyone lend a helping hand?
      Thank you!

      edit- first gen i7 860 12 gig ddr3 ram, asus p7h55m board, intel H55 chipset, asus gt 640 2gig card

      Hello and good day. I have never had this much problems with hackintoshes. I am working on my third hack.

      I was having boot problems, trying different flags, getting in, but never really fixing or setting up proper backups.

      I have many hhd's, a ssd as well. I have two usb sticks made mostly from #####. My ##### did not want to see my hdd (the installer)
      Anyhow, currently I have 10.13 installed onto my external drive. Used a niresh build, because i'm pulling hair.

      But even that does not see my HDDs or SSD.

      I'm guessing it is a clover or kext issue or driver, but I don't know anymore.

      Everything I do makes another problem. Anyhow, I have a fresh install (Actually I have 3 or 4 installs.

      My old one on SSD, another install on seperate HDD, and another fresh one.

      As far as I can tell the nvidia web drivers giving me issues, but I cannot get recovery to work to remove the kexts (as far as I can understand)

      On my external drive, it was giving me a problem. I was talking on the phone while the post-install screen was waiting, and than the system rebooted. I needed to boot in single user to delete the file that says the hack was setup, because when i restarted it just brought me to a blank login.

      Anyhow, I have work i need to do. I'm laughing though, I have never had problem after problem.

      I need to learn more. And everything is booting so slow. Just my HDD's and SSD and external drive.

      I know my clover installs and EFI partitions are too much, messed up config.

      I want to just wipe all the EFI's and just start fresh, but I do not know how?

      I guess linux boot disc maybe? Just delete the EFI's except one and only work on that?


      Any tips or walk through just to start fresh. Thank you for reading

      In this video I first show the boot time of my system running on an OCZ Vertex 3 SSD APFS formatted and with TRIM enabled. As you can see the boot has a long pause at these "FIPSPOST_USER" stuff. The solution that always worked for me is to create a time machine backup and restore to disk. As you can see after the restoring that long pause is drastically reduced. The initial boot time is 45 seconds circa, after restoring is down to 22 seconds. TRIM is still enabled and disk is APFS.
