In addition to what The Clever Monkey suggested, what you may want to try is to run the OS X "Activity Monitor". That sketch is running correctly on a 16x2 LCD as I type this reply. I uploaded the simple LCD Hello World example sketch to an Arduino Uno R3 board and it took about 3 seconds before the LCD began updating. OS X Version 10.7.4 (the latest version) and previous versions of OS Xīoth the latest version of the Arduino IDE (Arduino 1.0.1 from 5/2012) and the previous version have worked very well. I've used multiple versions of the Arduino IDE on a Macbook Pro purchased 6/2009 with
Note to forum moderators : you actually have to disabled smileys in order to have 10.6.8 appear without sunglasses. Is there a known performance gap between Lion & SL when running Java (I'm talking about a 20-30 performance multiple here).ĮDIT 2: In case proof was needed, definitely not a CPU issue, as running Arduino on Windows 7 inside a Virtual Machine on Mac Pro Snow Leopard compiles very rapidly indeed. I've checked Software Update for Java issues but I'm running the latest of everything.ĮDIT: Same slow performance on iMac 20" 2008 running Snow Leopard (same version as Mac Pro, 10.6.8). I now moved the Arduino to my 2009 Quad-Core Mac Pro and even "Blink" takes a minute or two to compile (with or without the Arduino plugged in), which is ridiculous.
Most sketches I've done compiled and uploaded in under 10 seconds. I've been working for a while with my Uno on an aging 2006 Core 2 Duo MacBook running Lion, and everything's been working fine.
