Windows, OS X and Linux life hacks

I didn't know this so I am sharing it

Windows OS
if you are in a directory using CMD and want to open explorer from that same place type in  "Start ." no quotes of course and explorer will open in that directory

Mac OS X
if you are in terminal and want to open finder in that directory just type in "open ." and you will have finder open.

Linux (I use CentOS7)
just create an alias with this command alias open='xdc-open &> /dev/null'

I hope you can profit from this

all lower case file names

if you need to convert every file to lower case in a folder in OS X this command will do that.

for f in *; do mv "$f" "`echo $f | tr "[:upper:]" "[:lower:]"`"; done

Creating a bootable USB or SD on OSX

First, verify the path to your SD card. You can do this by running the following command from terminal: 

diskutil list

The output shows a list of disks currently mounted on the system. Here's the relevant line from my output: 

/dev/disk3
#:                       TYPE NAME                    SIZE       IDENTIFIER
0:     FDisk_partition_scheme                        *8.0 GB     disk3
1:                 DOS_FAT_32 RPISDCARD               8.0 GB     disk3s1

In this case I can verify /dev/disk3 is my SD card because the TYPE, NAME and SIZE values are correct. 

If you have an existing partition on the disk you may need to unmount it, otherwise you'll get a "Resource busy" error message when you try to write the image. 

diskutil unmount /dev/disk3s1

Now to write the image file to the disk. Note the 'r' added to rdisk3 which drastically improves write performance by telling dd to operate in raw disk mode:

sudo dd if=RetroPieImage_ver2.3.img of=/dev/rdisk3 bs=1m

Depending on the size of your SDcard this may take a while. You can press CTRL+T to see the current status of dd. As an example for my Samsung 8GB SD card the write speed was 12MB/s the command took 11mins to complete.

HP 800 G1 upgrade 10.13.1 to 10.13.2

if you are going to upgrade from 10.13.1 to 10.13.2 follow these steps for a efforts free upgrade

first upgrade clover to r4334

then download the follow kext and put the in your kexts EFI folder

Lilu.txt version 1.2.1

NvidiaGraphicsFixup.kext 1.2.1 <- if you have an Nvidia graphics card

The reboot

now you can upgrade from the App Store to 10.13.2 - failing to do so will cause your 800 G1 to not boot

Hackintosh HP 800 G1 Tutorial Version 2.0 OS X High Sierra

This tutorial is created for test and experimentation, use at your own risk, always backup your data before creating experimental OS's.

Here are the steps to get OS X High Sierra running on a HP 800 G1, this process should work for SFF and tower models of the same type.

Bios version L01 v02.71 05/09/2017
ME Firmware V 9.0.31.1487
If your system does not have these versions you results may vary.

Bios settings
Apply bios defaults
Storage  - Storage options = AHCI

This tutorial is based on the method of installing OS X onto the hard drive from a real Mac running OS X 10.13, other methods will require additional steps and research

After you have installed OS X on the drive that your are going to put into the HP 800 G1, you will need to install Clover Boot loader version 4233 or higher. Make sure to install Clover on the disk that will be going into the HP.

Note: all these steps needs to be done on the real Mac, DO NOT install clover on your real Mac, go slow and verify before you proceed.

Select the options as pictured.














You will need to obtain the following files (google it and download it)

Clover_v2.4k_r4233
Clover Configurator 4.53
HWMonitor 6.25-333

AppleHDADisabler.kext 1.0.1
CodecCommander.kext 2.6.3
FakeSMC_ACPISensors.kext 6.25-333
FakeSMC_CPUSensors.kext 6.25-333
FakeSMC_GPUSensors.kext 6.25-333
FakeSMC_LPCSensors.kext 6.25-333
FakeSMC.kext 6.25-333
IntelMausiEthernet.kext 2.3.0d0
Lilu.kext 1.1.7
USBInjectAll.kext 0.6.2
VoodooHDA.kext 2.8.9


You will need to add the following Kexts to /EFI/Clover/kexts

The below are the Clover options you will need to apply using Clover Configurator
