Just switched to Mac (MBP). First application I am using is Audacity which is good as the interface is the same as the PC so not much effort to switch. But there are a couple problems. 1) When I do a "Save As" and begin typing the filename the program (Audacity) takes this as keyboard shortcuts! I can not believe it! When using the Save As dialog box the program executes the keys I push as part of the filename as shortcuts - so by the time I have typed the filename it has recorded, edited and screwed up the waveform. Surely when a Save As dialog is open and you are typing a file name the system should shut off keyboard short cuts to the app? This is a nightmare. 2) In the Save As dialog box generally, there seems to be no way to say with one click go back up one directory from current position - this is annoying. 3) On the PC I like Zooming in with Left button and Zooming out with Right button, but it seems on the Mac since there is only one button I have to go to the menu to get the other Zoom which is annoying as it takes much more time. 4) For export to MP3 I use the LAME plugin encoder. On the PC it is no trouble to get LAME but for the life of me I can not decipher where to get it for the Mac to plugin to Audacity.
