About me :-)

This is my personal site and is not affiliated with any companies I have or currently work for.  I will, in general, often be posting about technical information or solutions I have come across or created myself but this may not always be the case.  I do enjoy many things beyond the world of computers and those things may end up on this site from time to time.  At any rate, I hope what I post on here is useful to others and if not that is ok too 😉

Who I Am

My name is Chris Silvertooth and am married to my beautiful wife Amy. I also have 3 frenetic boys which keep me very busy when I am not messing with computers or other random projects.  I have been working in the computer industry for the last 14 years.  I previously worked as a Senior Consultant that was focused on Mac and iOS Integration.  I  am also certified in Linux and utilize VMware and other Datacenter technologies on a daily basis.  I am not a programmer but can cobble together some garbage that meets my goals.  I will, if it seems useful, post said garbage to my downloads section.

    I have successfully created the Recovery Partition with Recovery Partition Creator 3.7. I can use its features such as Find My Mac and FileVault.

    But when I try to start up to Recovery HD by holding Command-R, I get to blank screen with circle logo. Have tried several times. The result is the same.

    My mac is MBP 15″ Retina.

    Any Suggestion?

    Hey man, i don’t know how you did it but your Recovery Partition Creator helped me a lot!

    Thank you so much :))

    Have a nice day!

  3. Kevin says:

    Have you tested if this will work with 10.10 Yosemite?

  4. sanjin says:

    i dont have Mavericks onmy purchase history of mac app store so i am dowloading it from other means, downloaded recovery partition creator from your website.
    does that sound good?

    • Christopher Silvertooth says:

      As long as it is the installer it should work. I think the mavericks one is called “Install OS X Mavericks.app”

  5. Roger Kaufmann says:

    Hi Chris,

    Will Recovery Partition Creator work with Yosemite 10.10.2?

  6. Lewis says:

    Hi, I’ve a hard drive, 1tb that’s two partitions now, one Snow Leopard for some apps I need, and the other is Mavericks. I wanted to create a recovery part ion in the Mavericks partition, would the fact that I have two partitions now impact things? I don’t want to loose either one. I just want to carve a little out of the Mavericks partition to make it’s recovery partition.
    Thanks in advance!

    • Christopher Silvertooth says:

      Multiple partitions should be ok. I have multiple partitions on another mac without a problem.

    Your script Recovery Partition Creator 3.8 helped me set up a recovery partition on El Capitan in minutes!

  8. Alex says:

    I just used Recovery Partition Creator 3.8 to install recovery partitions on a couple of USB drives, in order to be able to clone (via Super Duper) my computer’s internal drive to them, and make them both encrypted and bootable. Thanks!

    I do have a question — my Mac, and the drives, are currently at Mountain Lion (to avoid surprises for other users in the family). I plan to update to El Capitan soon (it’s time …). Can I re-run RPC on the same drives but point to an El Cap installer, and have the OS and/or other things in the recovery partition updated to El Cap? Or if not, can you recommend a procedure that would accomplish the same goal?

    Thx again,
    — alex

      It has been awhile but I think I did that in the past. Though I would not boot to the recovery partition and run any utils as they might be incompatible and cause an issue.

    iMac late 2009
    I have used your Recovery Partition Creator with El Capitan before and it has worked ok, but after a recent apple update to v 10.11.1 the software is reporting “NOT COMPATIBLE WTH THIS SOFTWARE VERSION”. I hope this information is of use, your software has been a life saver in the past.

    Hey Chris

    Thank you many times for this tool, you saved me probably 4 days of reinstalling a bootcamp partition because csrutil was not available with online recovery mode ^^ and SIP blocked my backup

  11. Alain says:

    I’m on OS X 10.11.5 El Capitan.
    When I try to use “Recovery Partition Creator 4.0.1.app”, I get the following result: “The mainDrive variable is undefined” (“La variable mainDrive n’est pas définie”) and no installation is done.
    I chose the correct disk and “Install OS X El Capitan.app”.
    Is it possible that this is because I want to make this installation on the startup disk?
    Note: The download gives me “Recovery Partition Creator 4.0.1.app” but the info window give me “4.0 – Thursday 5th May 2016 – 4:22 p.m.”
    Thank you

    Thank you very much…
    But I still have the same problem with “Recovery Partition Creator 4.0.2.app” :
    “The mainDrive variable is undefined” (“La variable mainDrive n’est pas définie”) and no installation is done.

    • Christopher Silvertooth says:

      I updated to 4.0.3 a few hours ago. Give that one a shot. If you are still having a problem let me know.


  13. Alain says:

    Thank you for your involvement.
    Alas! Alas!
    With 4.0.3 (Recovery Partition Creator 4.0.3), I still get the same warning: “The mainDrive variable is undefined” (“La variable mainDrive n’est pas définie”) and no installation is done.

  14. Peter says:

    Hi, is there a solution for this problem?

    • Peter says:

      my partition scheme looks like:

      0: GUID_partition_scheme *500.1 GB disk0
      1: EFI EFI 209.7 MB disk0s1
      2: Apple_HFS OSX 499.8 GB disk0s2

    • Christopher Silvertooth says:

      Will be looking at the program next week. Seems Sierra introduced a number of changes that I need to look at.


  15. John says:

    Hi Christopher,
    I have the same problem that Alain and Peter with the mainDrive variable.
    I am using version 4.0.4 on Sierra.
    If you need logs or testing a new version, let me know
