MacOS / Networking / sysadminLeave a comment

This is the second part of the USB3 Gigabit on MacOS series. On the first post we discussed on how to choose an USB3 Gigabit adapter. On this post we try to answer to the following question: Does USB3 on MacOS supports gigabit speeds ? Read below to find out. To start with, let’s remember why it might be important for some users how does USB3 allows for gigabit ethernet performance: most recent MacBooks lack ethernet jacks. This means that, for power users, there are only a limited set of alternatives: Thunderbolt Gigabit adapters, for those laptops which support still …

USB3 Gigabit Ethernet adapters on MacOS: Orico Vs KY-688

Consumer Electronic Devices / MacOS / sysadminLeave a comment

Edit: This is the first half of a 2 part port regarding USB3 ethernet adaptors running on MacOS. The second part looks at actual performance. There aren’t a lot of good reasons why one would care about getting an USB3 Gigabit Ethernet adapter, and all start with “I need an extra wired gigabit connection”. And this may not be as weird as it seems as most MacBooks lack a single embedded wired gigabit interface. As an alternative you get the Thunderbolt adapter (in it’s native Thunderbolt port, or using the new USB-C connectors), USB3 adapter or 802.11 WiFi connection. Current state …

Radmin on Mac OSX

sysadminLeave a comment

It’s been literally years since I (and others) requested Radmin to add Mac OSX to the list of operative systems supported by the client version of Radmin Remote control. Actually one can actually see posts requesting this feature back in 2005. So much for listening to user’s requests…. … Well, enough is enough and it’s time to leave the Windows virtual machine, and use Radmin on Mac OSX through Wine and all it’s native beauty. It take a number of hours, but at the end it’s well worth the wait. Install Macports This step is only necessary if you don’t already …

sysadminLeave a comment

My old 13″ Macbook Pro’s 250GB is at it’s limit. It’s full and slow, and it is running Snow Leopard. So it was time to change it all. The old disk was a 250GB Hitachi HTS542525K9SA00 with a 5400RPM rotational speed, the new, a Seagate Momentus 750GB 7200RPM beast. The Plan? 1. Get the new hard drive onto a usb case 2. Install Snow Leopard on it 3. Install Lion on the usb drive Ad 4. Check if all the applications are ok 5. copy all the data from the old drive to the new one (*) 6. Install the new …

Recover data from a non booting Macbook Air (OSX 10.6 and 10.7, and probably 10.8)

sysadmin3 Comments

The Macbook Air is the best tool for someone whose main function is to attend to meetings. Although the new (2011) models all feature SSDs, the older models only offered those as an option. As such, even the best build machines are not free from hard drive failures, which remain as the component with highest failing component. Regardless, in case you get stuck with a non booting Macbook Air,  here’s how to recover the data: 1. First, why does this even works? Simple. OSX uses a kind of file system called “Journaled“, which is far different from FAT or NTFS, …

sysadminLeave a comment

Recently i’ve been fighting some performance issues with Spotlight on OSX 10.6. As sad as it may seem, the problem is not on Spotlight it selft, but on it’s reliance on third parties to search inside files. On my case, the issue is related to Office 2010 Exel files: Jul 26 10:52:51 macbook-2 mdworker32[18995]: (Normal) Import: Spotlight giving up on importing file /Users/xxx/Library/Mail/Mailboxes/xxx/xxx.mbox/Attachments/156147/2/_excel_filename_.xlsx after 240 seconds, 235.697 seconds of which was spent in the Spotlight importer plugin. Which makes Spotlight take DAYS for index all my files and emails. Regardless, the way to ckeck what Sportlight is actually doing is …

HTC Magic tethering with Linux and OSX Snow Leopard without Android’s root permissions

MobileLeave a comment

Editor’s Note: Unfortunately, my HTC died just before I finished posting this, so not all steps were thoroughly tested although I did test the end results on both Snow Leopard and Linpus. For all those still waiting for HTC to update it’s Magic smart phone to Android 2.2, where not a lot of options for tethering you device with Linux or OSX machines: root it, pay for PDAnet (and it only works on OSX), or follow the following steps 🙂 How it works Android 1.6 doesn’t offer any capability to use a cell phone as a simple UMTS Modem, as …
