Building for Windows/Linux on Newer Macs

We have discovered what we believe to be a bug in OS X Mavericks specifically on newer Macs. Apple started using Intel’s new Haswell processor in the MacBook Air in June, the iMac in September and the MacBook Pro in October. When you build for either Windows or Linux from OS X, any images you dragged into your project are converted to BMP format. The bug we discovered (which we have reported to Apple – RADAR case 15546907) results in a banding of the converted graphic.

Xojo Apps in the Mac App Store

Is it possible to put a Xojo-made application in the Mac App Store?

The answer is simple: Absolutely.

However, it can be a lot of work and you’ll have to pay heed to Apple’s rules regarding the Mac App Store and follow their very stringent requirements.

Merging iCloud and Apple ID Accounts

iCloud.jpegIf you have been around the Mac community long enough, you may have ended up with two Apple IDs. I have one for iTunes and another one that came from MobileMe. This resulted in effectively having two iCloud accounts. This can be inconvenient and probably will become more so in the future. Apple doesn’t provide a means to merge Apple IDs. They know they need to provide this, but they do not yet do so. I, however, have found a way.

Since the introduction of iCloud, I have wanted to have a single Apple ID. When Apple recently added the two-step authentication for Apple IDs to make them more secure, I decided to sign in and update my Apple ID account. Part of the process is to verify a device you own which will be used, along with your password, to authenticate that you are who you say you are should you want to make changes (such as your password) to your Apple ID in the future. The webpage said it would list my devices, but none were listed. It didn’t take long to figure out why. The Apple ID I was updating was for iTunes, while the Apple ID Apple was using to find my devices was the one associated with my iCloud (MobileMe/mac.com) account.

More Important Than Ever: Cross-Platform’s History

There was a time when the idea of running the same code on different computers wasn’t even imagined. Programming languages were written specifically for a particular computer. And computers were purchased for very specific purposes so why would you even want to run a particular program on another type of computer?

It was the desktop computer revolution that changed that. By the mid-to-late 1980’s, there were more and more desktop computers and developers wanted to target all of them. Soon, however, Windows became so dominant that many developers chose to focus on that one OS. Some Mac developers, not wanting to miss out on the potentially enormous Windows market, either went to the trouble of writing two versions of their applications or used a tool/language that would allow them to target both Mac and Windows from a single code base. This was the beginning of cross-platform development.

Recently, I was asked by tech blogger Chris Pirillo if cross-platform was really important anymore. Cross-Platform is actually more important than ever. Why? First of all, while the Windows PC market is seeing flat or declining sales, Apple’s Mac marketshare is growing. We are seeing this at Xojo. More and more Windows developers are coming to us because they can no longer ignore the Mac market. Linux is the predominant server OS. If you want to write server software that can run on some combination of Linux, Windows and OS X, you’ll want to be writing cross-platform code.
