New Hackintosh: HP EliteBook Folio 9470m

By , 2017-04-01 00:23

Update: The macOS Sierra 10.12.4 update breaks backlight brightness control. See below for fixes.

Just in time for April Fools’ day, got a new hackintosh working. And this one even looks like a MacBook Pro!

I present to you, the EliteBook “Pro” (9470m).

EliteBook “Pro” 9470m. Please excuse the messy desktop icons.

The EliteBook 9470m was, if I recall correctly, HP’s second Ultrabook, and their first true “Enterprise” Ultrabook – that is, one with docking capability and easy field repairability . You can find a full review over at NotebookCheck.net.  It was pretty popular with businesses who wanted to give their employees a more affordable and more IT-friendly “MacBook-like” device. Also, it was released back in late 2012, which is just over 4 years ago as of this writing. (Crazy! Time flies.) This means that they can be had relatively cheap in the off-lease market today, as the typical computer lease is between 3-5 years. My local computer store is selling them for under $400, which is a pretty good value in my opinion.

These days, installing macOS is relatively easy compared to 10-12 years ago when I first started messing with Hackintosh/OSx86, so I’ll just post my Clover “EFI” folder which should get you booted into macOS Sierra on the 1366×768 version of the 9470m. I did also swap out the Intel WiFi card for a Dell DW 1510 which works out-of-the-box.

Download my Clover EFI folder (zip 19MB): EFI 3  See below for 10.12.4 brightness fix

Working:

  • Internal graphics with full acceleration, brightness control using scroll lock/pause-break keys
  • Sound via VoodooHDA (built-in mic, speakers as well as TRRS headset jack. Volume and Mute fix in Info.plist necessary)
  • Touchpad with 2-finger scroll
  • Internal PS/2 keyboard
  • 3 USB 3.0 ports
  • Wired gigabit Ethernet
  • WiFi (replacement DW 1510 Broadcom card)
  • Built-in webcam

Not working:

  • Sleep (wakes up instantly)
  • Original Intel 6235 WiFi + Bluetooth
  • TrackPoint/Nub/Nipple mouse
  • Validity Fingerprint reader
  • WiFi on/off button

Not tested (yet):

  • Docking
  • VGA-out
  • DisplayPort-out
  • HDMI Audio
  • SD Card Reader

I will updated the lists as I test more things.

Main reference for this was RehabMan’s Elitebook guide.

10.12.4 Backlight Brightness control fix

Download updated EFI folder (zip 19MB): EFI 10.12.4

Fixes included:

  • Removed NullCPUPowerManagement.kext
  • Updated VoodooHDA.kext/Contents/Info.plist to include Mute Fix
  • Added SSDT-PNLF.aml in ACPI/patched as per guide
  • Edited config.plist to load SSDT-PNLF.aml
  • Fixed backlight control (using this guide)
    • Re-patched DSDT in MacIASL with the following fixes only from “RehabMan-Laptop”:
      • battery_HP-ProBook-4x0s-G1.txt
      • graphics_Rename-GFX0.txt
      • graphics_HD4K_low.txt
    • Added AppleBacklightInjector.kext

Extra .kexts for SD card reader: JMicron.zip

Taking back control of updates in Windows 10

By , 2017-01-15 18:35

Microsoft’s latest OS brings a lot of improvements and changes to Windows. One particularly significant change is the way Windows Update works. By default, Windows Update will decide on its own when it wants to restart your computer – be it in the middle of rendering video, uploading or downloading a large file, or even in the middle of a competitive gaming session:

There are a few steps you can take however to make living with Windows 10 more bearable and stop it from interrupting activities on your computer.

Unfortunately, these steps only work on Windows 10 Pro, Enterprise and Education editions.

Part 1: Local Group Policy

  1. Run the Local Group Policy Editor tool by typing “gpedit.msc” into the Run dialog box.
  2. Navigate to Computer Configuration > Administrative Templates > Windows Components > Windows Update
  3. The policies we are interested in are Configure Automatic Updates and No auto-restart with logged on users for scheduled automatic updates installations.
  4. Set both policies to Enabled, then for Configure Automatic Updates, configure the options as shown:
    2 – Notify for download and notify for install
  5. This should take care of preventing your computer from restarting automatically when it feels like it.

Part 2: Disabling Updates are available nag screen

OK, so now you’ve got the automatic updates disabled. But you’ve been a bit lax with your updates and haven’t manually installed them in a while. So Windows 10 presents you with this:

Which is good, because you really should keep your computer up-to-date for both your own and others’ security online.

However, there are some cases where this screen can be incredibly annoying – on a digital signage box, on an HTPC, or on a gaming computer for example – since it interrupts whatever you are doing with an un-closeable prompt, much like adware.

The good news is that there is a way to disable it. It’s a bit less “official”, so it may not work for you, but so far so good for me.

From an elevated Command Prompt, run the following commands.

cd /d "%Windir%\System32"
takeown /F MusNotification.exe
icacls MusNotification.exe /deny Everyone:(X)
takeown /F MusNotificationUx.exe
icacls MusNotificationUx.exe /deny Everyone:(X)

Warning: I don’t advocate running commands without knowing what they do or trusting the source, and since you might not trust me, I’ll explain what the commands do.

First we Change Directory (cd) to the Windows system32 folder. Then, we take ownership of the file MusNotification.exe and deny Everyone (including the system itself) from eXecuting it. Then we repeat the process for MusNotificationUx.exe.

And that’s it!

Discs that can be used to configure AccurateRip on a new drive

By , 2016-12-17 16:11

Was just setting up EAC to use a new external Blu-Ray drive, and had some difficulty finding eligible key discs – discs that have only one pressing and are known to the AccurateRip database.

EAC needs 3 discs to correctly confirm the drive’s offset.

The discs I used were:

  • Hey Rosetta! – Seeds | Sonic Records 2 000018
  • Hey Ocean! – IS | Nettwerk 0 6700 30972 2 2
  • Taylor Swift – 1989 D.L.X (Deluxe) | Big Machine Records/Universal Music Canada BMRB0550E

Saving here for future reference to avoid me having to go through a pile of CDs next time I need to calibrate EAC for a new drive.

My convoluted Subsonic server setup

By , 2016-05-15 21:23

Since ending my colo server plan, my Subsonic server hasn’t been running. I used to just have all my media synced to the Proxmox server I had in colo, then bind-mounted that folder to the OpenVZ container that was running Subsonic.

I’ve now moved my Proxmox/Subsonic server to a little Zotac ZBOX on my LAN that only has one local disk so I figured I wouldn’t sync all my music over locally when it could just directly access it from my new FreeNAS box. Turns out this is a little bit more complex than I thought – here are the steps I did to get it working:

  1. Get all music onto the FreeNAS box. For this I’m still using BTsync. One client is on my Mac, sharing my iTunes library, the other is in a FreeNAS jail.
  2. Install Subsonic in an LXC container on the Proxmox server.
  3. Create an NFS export on the FreeNAS server and mount it as storage on Proxmox. I just used the “Add storage” option in the Proxmox Web UI rather than adding it to fstab, because I was lazy.
  4. Configure the LXC bind mount. Essentially, in /etc/pve/104.conf :
     mp1: /mnt/pve/freenas,mp=/mnt/freenas
  5. Set up Subsonic to scan the /mnt/freenas/music folder.
  6. Realize that Subsonic has issues with non-ASCII characters in filenames. Fix it by adding “export LANG=en_CA.UTF-8” to the subsonic.sh start script.
  7. Realize that Subsonic has no access to write to the NFS share, since the GIDs on the FreeNAS box and the Subsonic container don’t match. I use GID 500 = users as my main group on FreeNAS, so I created a group freenasusers with GID 500 in the Subsonic container and added the subsonic user to this group.

Probably missed some steps, but that’s the gist of it. I really need to get my blogging and documentation back on track.

How to get postfix to deliver root’s mail locally when using a smarthost

By , 2015-12-09 10:40

When setting up Postfix on Ubuntu/Debian as “Internet Site with smarthost” to use an external smtp relay, automatic e-mails intended for “root” (such as cron job error reports) get sent out to the smarthost with a To: address of [email protected] This can cause a problem as the smarthost doesn’t know where to deliver these messages to, since myhost.mydomain.com has no MX record.

The fix for this is (go figure) in the Postfix README:

Delivering some but not all accounts locally

A drawback of sending mail as “[email protected]” (instead of “[email protected]”) is that mail for “root” and other system accounts is also sent to the central mailhost. In order to deliver such accounts locally, you can set up virtual aliases as follows:

1 /etc/postfix/main.cf:
2     virtual_alias_maps = hash:/etc/postfix/virtual
3 
4 /etc/postfix/virtual:
5     root     [email protected]
6     . . .

Translation:

  • Line 5: As described in the virtual(5) manual page, the bare name “root” matches “[email protected]” when “site” is equal to $myorigin, when “site” is listed in $mydestination, or when it matches $inet_interfaces or $proxy_interfaces.

Execute the command “postmap /etc/postfix/virtual” after editing the file.

Oddly, just adding the line

root: [email protected]

to /etc/aliases doesn’t work. You really need to do the steps outlined in the manual.

The magical feeling of being a sysadmin

By , 2015-04-07 21:18

It’s really cool what we can do with computers these days. I generally take technology for granted, but sometimes I am just in awe of what is possible.

 

4381851322_998492c432_o
With the ubiquity of the Internet
It’s all too easy to forget
How amazing it is, that with relative ease –
Just a few strokes of the keys
A sysadmin can ssh to a box running Unix
On the other side of the world, or just across town.
And with just a few clicks
Bounce that Windows box that’s gone down.

Written for OPS235 Course – Software and Installation Process

By , 2015-03-29 23:30

lamp-featuredSoftware installed

Apache

Apache is an open-source web server software maintained by the Apache Software Foundation and the open-source community. It can be extended using modules, and is well-documented and well-supported. It is usually the de-facto standard Web server on Linux, although lately new and customized Web servers such as nginx have been becoming more popular for dynamic, high-traffic sites.

PHP

PHP is a server-side scripting language mainly used for web development. By writing PHP rather than plain HTML, developers are able to create pages that are dynamically generated by the server on the fly depending on parameters provided. The Zend PHP interpreter is open-source software, and is available as a module for multiple Web servers on Linux, Windows, BSD and other OSes.

MySQL

MySQL is an open source relational database management system (RDBMS). It is open-source software, released under the GPL and sponsored by Oracle Corporation. The software is available at no cost, although there are also some paid versions. It has widespread use in Web applications, such as WordPress and MediaWiki, and is also used by large sites such as Facebook and YouTube.

LAMP stack

Together, CentOS (Linux), Apache, MySQL and PHP form an implementation of a LAMP stack. This stack provides a consistent, portable environment for Web developers.

WordPress

WordPress is an open-source blogging platform and CMS. It is written in PHP, and uses a MySQL database for text content storage and metadata. It provides an easy-to-use user interface, and is highly extensible and customizable with a large number of user-creatable themes and plugins. WordPress powers some prominent sites such as Forbes.com, vogue.com and nationalpost.com.

Problems encountered during installation

  • The systemctl command was not available, since this install of CentOS is using upstart rather than systemd.
  • There was no default index page created during the install of httpd. As a result, accessing HTTP on the Centos3 VM server gave an HTTP error 403 (Access denied) – the default Apache configuration denies directory listings.
  • The c6host machine was not able to access the HTTP service on centos3 because its iptables was not configured to allow inbound traffic on port 80.
  • When configuring iptables on centos3, running iptables -A INPUT -p tcp –dport 80 -j ACCEPT was notsufficient.
    • The -A option appends the rule to the end of the INPUT chain, however, there was a pre-existing explicit rule rejecting all packets.
       REJECT     all  --  0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited
    • To move the new rule above the reject rule, the incorrect rule had to be removed by running iptables -D INPUT -p tcp –dport 80 -j ACCEPT
    • Then, find the line numbers by running iptables -L –line-numbers
       Chain INPUT (policy ACCEPT)
       num  target     prot opt source               destination
       1    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0           state RELATED,ESTABLISHED
       2    ACCEPT     icmp --  0.0.0.0/0            0.0.0.0/0
       3    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0
       4    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:22
       5    REJECT     all  --  0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited
    • Use iptables -I INPUT 5 -p tcp –dport 80 -j ACCEPT to insert the new rule above the existing rule 5.
    • Running iptables -L –line-numbers again gives the following output:
      Chain INPUT (policy ACCEPT)
      num  target     prot opt source               destination
      1    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0           state RELATED,ESTABLISHED
      2    ACCEPT     icmp --  0.0.0.0/0            0.0.0.0/0
      3    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0
      4    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:22
      5    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           tcp dpt:80
      6    REJECT     all  --  0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited
  • The contents of the WordPress .tar.gz file were extracted to /root/wordpress. Moving this directory to /var/www/html resulted in the Apache process not being able to read the wordpress subdirectory. Copying (cp -R) avoids this issue.
  • When configuring the WordPress connection to MySQL, the WordPress documentation said to run the query
    mysql> GRANT ALL PRIVILEGES ON databasename.* TO "wordpressusername"@"hostname"
        -> IDENTIFIED BY "password";

    to allow access to the database. However, since the MySQL server and Apache/WordPress are installed on the same host, we need to use “localhost” rather than “centos3” for the hostname.
