Acorn's Frequently Asked Questions
Where can I find old versions of Acorn?
Here is a list of links to older versions of Acorn, just in case you need one for some reason. However, you should always be running the latest version of Acorn since it has important bug fixes that older versions do not contain.
Acorn 1.5.5, for use with 10.4 and later: http://flyingmeat.com/download/Acorn-1.5.5.zip
Acorn 2.6.5, for use with 10.6 and later: http://flyingmeat.com/download/Acorn-2.6.5.zip
Acorn 3. for use with 10.6 and later: http://flyingmeat.com/download/Acorn-3.5.1.zip
Currently Acorn 4 is the only version for sale.
I'm not running 10.8+, can I still use Acorn?
Acorn 4 requires 10.8+. Both Acorn 2 and 3 require 10.6+. Acorn 1.5.5 runs on 10.4+. If you wish to purchase Acorn 1 or 3 go ahead and buy Acorn 4. Email email@example.com and let us know your registration name and number. We will create an Acorn 1.5.5 or Acorn 3 registration for you. The Acorn 4 registration will not work in previous versions.
Why does Acorn have a button labeled "Purchase" in the window?
Acorn runs in two modes: "paid", and "trial". In trial and paid modes all the functions of Acorn are operational. If you see the "Trial" button in the upper right hand corner of the canvas window, that means Acorn is in trial mode. If you like Acorn, you can click where it says 'trial' in order to make the purchase. After the 14 day trial period has ended, a watermark will appear over your images. No worries- you can purchase Acorn (by clicking on purchase) to make the watermark go away!
Why is it cheaper to upgrade to Acorn 4 at the Flying Meat Store than the Mac App Store (MAS)?
The Flying Meat Store (http://www.flyingmeat.com/store) offers Acorn upgrades for $29.99. The Mac App Store only allows one level of pricing for Acorn, so we cannot offer a discounted upgrade price. The price at the MAS will be the current full price of Acorn, and we cannot give credits or refunds for the difference. Some users feel the extra cost at the MAS is worth it for the convenience of the store and other benefits the store offers.
I bought Acorn on the Mac App Store. Why am I still running the trial version?
You will need to delete the trial version of Acorn from your computer. Perform a spotlight search for "acorn kind:app" (without the quotes). Delete all copies of Acorn that are not located in your Applications folder. Install or re-install Acorn from the Mac App Store. It should be listed under your 'Purchases' tab. If you clicked the 'Install' button and Acorn isn't showing up in your applications folder once it has completed installing, try re-booting.
I bought Acorn on the Mac App Store. Where's my registration number?
The Mac App Store does not provide a registration number for Acorn, since the store manages all the applications you purchase through it for you. You will notice in Acorn preferences that there is no registration tab if you bought Acorn on the App Store.
How do I upgrade to the latest version of Acorn?
If you bought Acorn from the Flying Meat Store: Open Acorn. If a dialog box doesn't pop up telling you about the latest version, you can select Acorn ▸ Check for Updates. You will be guided to download the latest version of Acorn if you don't already have it. For paid upgrades, you will be placed in 'trial' mode. If you wish to upgrade, click where it says 'trial'. Your previous registration number should self populate in the Flying Meat Store and you will be guided to provide payment.
If you decide you want to stick with the previous version and do not want to upgrade, delete the latest version of Acorn from your computer. You can download the previous version via the links shown above under 'where can I find old version of Acorn'.
If you bought Acorn from the Mac App Store: Updates are managed through the store under 'Updates'. At this time the Mac App Store does not allow for decreased pricing for upgrading to a new major release.
I have an Acorn 1 license, can I upgrade to the latest version of Acorn with that?
Yes! If you have a registration number from any previous version of Acorn, you can use it to upgrade to the latest version. However, you can only use that registration number once for an upgrade (meaning, you can't use it, and then let your friends use it as well).
Can I use the same registration on multiple computers?
Yes, you may use your Acorn registration on multiple computers as long as it is only you using the license. And if you have a single Mac with multiple people using it, you do not need to purchase an additional license. However, if you have multiple computers and multiple people wanting to use Acorn, you will need to buy an additional license for each computer.
Does Acorn support Photoshop files?
Acorn does its best to open PSD images, and if possible, preserve layers. Photoshop styles, and editable text are not supported however. To save a layered PSD file, choose the File ▸ Export menu, and select PSD from the Format menu.
I'm a student, can I receive a discount on Acorn?
Yes, Flying Meat offers a $15 discount on Acorn for students through our store only. We require that you send the request to firstname.lastname@example.org using your student email address ending with .edu. We will then send the discount code to your student email address. The student discount cannot be used for upgrades, and is not available during promotions and sales.
What is the recommended resolution for printing?
This is a complicated topic. In general a PPI (pixels per inch) of around 200 - 300 gives good printing results. Read more here about the relationship between pixels display and printing. You can also check out our tutorial: "All about DPI, PPI, and Printing".
Is there an online forum for Acorn?
Yes! Check out Acorn discussions and topics at Flying Meat's forum: http://forums.flyingmeat.com/
