Why can I not split a .ape file?

I would like to split a .ape album into individual tracks in .flac format using a .cue sheet. For this I followed a tutorial I found. In short I pass this command to the terminal: cuebreakpoints example.cue | shnsplit -o flac example.ape But I get the following error back: shnsplit: warning: failed to read data from input file using format: [ape] shnsplit: + you may not have permission to read file: [example.ape] shnsplit: + arguments may be incorrect for decoder: [mac] shnsplit: + verify that the decoder is installed and in your PATH shnsplit: + this file may be unsupported, truncated or corrupt shnsplit: error: cannot continue due to error(s) shown above Unfortunately I don't know how to overcome this issue. One thing I think can be discarded is the file being corrupt since I had the same error with another .ape and I have followed this procedure with origin .flac files with no problem. How can I solve this problem?
