If money is no object, and you like the mac ecosystem and support structure buy a mac. If money is a factor, you can live happily with the windows ecosystem then get a windows computer, don't stretch your budget for a mediocre mac option when you can buy a considerably better windows system for the same money unless you feel you have to work in. . Scientists require administrator privileges on their mobile machines. This situation is not restricted to Linux. The situation applies to Windows, and the MAC. Scientists need control of the machines to add software and to troubleshoot. Most scientists who have Linux or MAC OS X have been administrating their own systems for a long time. Feeding tata mac os. A modern version of OS X: openconnect is should work on most recent OS X versions. It has been tested and seems to function correctly as far back as 10.9.

System Requirements
- A modern version of OS X: openconnect is should work on most recent OS X versions. It has been tested and seems to function correctly as far back as 10.9.
- Mac OS X TUN/TAP driver, which allows for creation of the virtual network interface.
Installing openconnect
Install using homebrew or macports
The built openconnect package is available using macports or homebrew. You can install using one of these two programs, then install the TUN/TAP driver. You will need administrative privileges on the machine you are installing this on.
- Install homebrew or Macports.
- Open Terminal and update the package cache using the command
- Install the openconnect package using the command:
- If using macports, you can use the command:
- Install the Mac OS X TUN/TAP driver
- Optional: If you would like to run openconnect without admin privileges, you can add a line to your sudoers file to allow this. The line could look something like this:
Building from source
For advanced users only
Building openconnect from source will not be necessary for most users, as in general the prepackaged version from macports or homebrew will fulfill most needs. If you need the most recent version and it is not available, you can build it yourself.
- Ensure you have the dependencies needed for the package.
- Install the vpnc script to /etc/vpnc/vpnc-script
- Check the source code out from the openconnect Git repository or download a tarball from the openconnect website.
- Untar the code to a directory and build and install it with:
- Optional: if you would like to run openconnect without admin privileges, you can add a line to your sudoers file to allow this. The line could look something like this:
Running openconnect
- From the Terminal, run
- You will be prompted for your Kerberos password, and then the VPN client will connect.
- Once connected, you will have an IP address that begins with 18.100. You can verify this using ifconfig, and checking the address for tun0.
To disconnect, simply press Ctrl-C in the terminal window to end the program.

My new OpenZFS on Mac OS X setup in my cabinet, with raidz over 4x 1TB SSD on two AC powered USB 3.0 hubs. I ran into these gotchas:- The USB 3.0 UASP adapter I'm using sometimes changes the disk serial number, which causes zpool difficulty finding the disk after unplug or reboot. Fix: do a
zpool export
followed byzpool import
immediately after pool creation renames the disks in vdev to use media ID, which is more robust. The media IDs are created the same time the disks are added to the pool and automatically partitioned and formatted (with the GPT scheme), so you can't create a pool with disks referenced by media IDs. - If a disk is lost due to serial number change, the only way to get it back is by creating the missing symlink under /var/run/disk/by-serial manually and export then import the pool again. ZFS does not allow replacing a disk that is still part of a pool.
- When running
zpool import SomePool
withumask 0077
, the parent '.
' directory of/Volume/SomePool
becomes accessible only to root and permission denied for all other users, which causes the Finder to crash when creating folders. The Finder also displays existing directories (created in Terminal) as a blank document with no content. Just export and rerunzpool import
after settingumask 0022
. - ZFS by default is case sensitive. Some application bundles are built incorrectly, which causes a variety of errors when I open the application such as 'You can't open the application _______ because it may be damaged or incomplete' or 'The application cannot be opened because its executable is missing.' I ended up creating a dedicated Applications filesystem under the pool with
casesensitivity=insensitive
option (which can only be set when creating a filesystem). - Remember to set
zfs set com.apple.mimic_hfs=on
if you're planning to store Photos library on it.
I'm still experimenting with this setup, and in the process managed to toast an older 512GB SSD because one of my older USB 3.0 to SATA adapters had a bad contact, causing rapid power losses that fried the NAND. Trying to read/write problematic blocks would cause the drive to stall. But I managed to wipe it (under Mac OS X) by using VirtualBox running Ubuntu. Make sure the VM setting supplies USB 3.0 devices, or you'll get VERR_PDB_NO_USB_PORTS when attaching the USB/SATA adapter to the VM. Assuming the device shows up in the Linux guest as /dev/sdb (please double check, as this will be destructive), run:
After this, the SSD is empty and in a clean slate, and I could then format it.
Initially it seemed to be a good idea to use USB 3.0 hub and a bunch of USB 3.0 to SATA adapters to accomplish the disk array because it's much cheaper than an enclosure, but I've had many problems with it. The USB 3.0 hub sometimes incorrectly recognizes some adapters as USB 2.0 only, and this limits the speed of the whole array to USB 2.0 speed. I've also experienced flaky ports causing checksum errors. There are too many components that could go wrong and did go wrong, so I'm now getting a proper RAID enclosure as I should have in the first place.

The drive died again after writing some odd GBs of data on it. It seems that TRIM limits the number of blocks it can operate on at once, so I didn't actually wipe the whole disk. I also tried ATA secure erase but the drive died again, so it didn't seem to free up the blocks. I concocted a script:
Even though it stalls from time to time requiring manual intervention, it does seem that the more blocks I unmapped, the more I could write, so I'm hopeful.
