"Xcode6.dmg" Reason = image not recognized. "The following disk images couldn't be opened" open package content and run XCode6.2.dmg.The file is still named "Xcode_6.2.dmg.crdownload". The problem is that the download comes to 2.6/2.6 and does not finalize it. I had multiple network errors, connection breaks and it this isn't my problem. beta 5 but can't download the full version. ![]() I tried upgrading it and it doesn't work. Best “perceivable” thing I ever did to an 8 core 2008 Mac Pro. A $80 120GB SSD is more than enough for the system, Rhino, and a bunch of other apps. (Hint - your FW800 drives are not optimal for your “next” Mac) Add the $20 USB3 enclosure at purchase and you are set to utilize your SSD investment as a speedy little external in future. However, IMO, this makes most sense only if you plan to re-purpose the SSD when the old Mac does go out to pasture. Is your old Mac worth such…perhaps not, still, a SSD and a fresh OS, and your old Mac will say 60 is the new 40! (30?) Assuming it does not die of something else thereafter. The most “perceivable” speed upgrade during every day use is going from a standard drive to an SSD, especially the drive in your iMac. If you can spare $100…some might consider the following throwing good money after bad, and such is correct… unless… ![]() There is no “right” way really, depends on you. Overkill for most, unless you run an IT department. Now, let’s really complicate…you can create a cloned disk image and replicate: Still, good to become comfortable with a manual build from a boot drive. In addition to the drive swap, you could do so virtually with Carbon Copy Cloner from the external to the iMac internal: I think I will try John’s suggestion and attempt to install Mavericks on a spare external Firewire hard drive I have, from which I will then try to boot via Startup Manager.Īlways more than one way to whack a Mac. Since I am also not in the market for a new computer at the moment I was looking into the possibility of upgrading my old warhorse to Mavericks. As I mentioned in my original post I recently completed the Level 1 training course, and it became obvious that my current OS may not be the right one for it, even though it is a recommended OS by McNeel. For the last 4 months or so, I have begun to make good use of RhinoMac. First about 2 years ago, at which time I could not accomplish much with it. That program has become very long in the tooth, especially with the advent of 3D printing which allows me to make prototypes of my work. ( ) I have used trueSpace 3.1 for all those years. I have been working in 3D modeling for 17 years for visualizing my designs and presenting them to clients. You could make a TimeMachine backup of the old system to the external and then restore just your local account to the whacked local drive, though a pure clean install every few years is best opposed to constant upgrades and/or account migrations. If you are able and conformable, spent the time to “whack” it and reinstall everything (download latest versions for 10.9.x). Often, problems people have are a result of “upgrades” (multiple ones) and/or new OSs. You would do that with the external boot drive John recommends. However, often the best thing to do to an old system is to “whack” it…a highly technical term meaning - re-partition, format, and install a clean OS. You can conclude a lot with ease and will have a useful tool. This is an excellent suggestion for the flexibility it afford: the ability to test without mucking with an installation troubleshoot rebuild, all without affecting the in place system. You can even use that external drove on another Mac to test out different hardware combinations. Then you can boot to it when you want it and can easily go back and forth. ![]() Instead, I would install Mavericks on a FireWire external drive. ![]()
