OSXでgitkを使う

OSX(macOS)でgitkを起動しようとすると以下のメッセージが出て起動できない。

Error in startup script: 
    while executing
"exec osascript -e [format {
        tell application "System Events"
            set frontmost of processes whose unix id is %d to true
        end te..."
    invoked from within
"if {[tk windowingsystem] eq "aqua"} {

    (file "/usr/local/bin/gitk" line 12212

当該execをcatchで囲うとよいらしい。
